Oil/gas boilers refer to boilers whose fuel is oil or gas (such as natural gas, biogas, blast furnace gas, liquefied petroleum gas, diesel oil, light oil, etc.), and can be divided into steam boilers and hot water boilers according to their functions. Oil/gas boilers are special equipment and a type of pressure vessel. In addition, the fuel is flammable. Based on the particularities of this type of equipment, the safety of its operation must be guaranteed. The following six elements are required: 1. Explosion-proof doors must be set on the boiler body and flue; 2. Gas leakage alarm devices and ventilation equipment must be installed in the gas boiler room; 3. There must be a strict sequence control system for the start and stop of the gas boiler; 4. The burner must be equipped with automatic flameout protection device; 5. The pipelines of gas-fired boilers must be checked frequently, and there must be a necessary interlocking protection control system in the furnace; 6. The stoker of the gas boiler must be a full-time person in charge, and conduct regular and fixed-point inspections of the gas boiler. Yuanda oil/gas boilers have complete safety accessories: such as explosion-proof doors, fire holes, safety valves, pressure gauges, water level display and alarm, complete safety interlocks, etc., which can realize unattended and fully automatic safe operation.

1. Steam boilers and heat transfer oil boilers are used as heat source equipment for drying, cooking, sterilization, disinfection and pulping in food, chemical, pharmaceutical, paper, printing and dyeing industries. Steam boilers are mostly saturated steam, and the steam temperature is proportional to the boiler pressure. The higher the pressure, the higher the temperature. The design pressure of the heat transfer oil boiler is generally 0.8 MPa, and the outlet temperature of the medium is about 320 degrees. Second, the definition of steam boiler: The heating equipment (burner) releases heat, which is first absorbed by the water wall through radiation heat transfer, and the water in the water wall boils and vaporizes, generating a large amount of steam into the steam drum for steam-water separation (except for the once-through furnace), and the separated saturated steam enters the superheater. Continue to absorb the heat of the flue gas at the top of the furnace, horizontal flue and tail flue through radiation and convection, and make the superheated steam reach the required working temperature. The boiler for power generation is usually equipped with a reheater, which is used to heat the steam that has passed through the high-pressure cylinder to do work. Steam boilers can be divided into gas-fired steam boilers, oil-fired steam boilers, coal-fired steam boilers, biomass-fired steam boilers, etc. according to the fuel; 3. Definition of heat transfer oil furnace: Heat transfer oil, also known as organic heat carrier or heat medium oil. The heat transfer oil boiler is a boiler that uses heat transfer oil as a heat medium for heat transfer. Using the high temperature characteristics of heat transfer oil, the heat transfer oil boiler can realize low pressure and high temperature heating. Because the use of heat transfer oil heating has the advantages of uniform heating, simple ope

1. Induced air equipment: The flue gas generated in the operation of the boiler is sent to the atmosphere through the induced draft fan and the chimney. 2. Dust removal equipment: remove fly ash from boiler flue gas. 3. Fuel supply equipment: function of storing and transporting fuel. 4. Feed water equipment: The feed water treated by the water treatment equipment is sent to the boiler by the feed pump. 5. Dust removal and slag removal equipment: remove ash and slag from the boiler and transport it away. 6. Air supply equipment: The air heated by the air preheater is sent to the furnace and the coal grinding device through the air supply fan. 7. Automatic control equipment: automatic detection, program control, automatic protection and automatic adjustment. As a leader in the industrial boiler manufacturing industry, Yuanda Boiler is not only responsible for providing boilers, but is also committed to providing users with a complete boiler system and effectively improving the benefits of users.

Compared with assembled boilers and bulk boilers, quick-installed boilers refer to the fact that manufacturers have basically completed the above installation work in their own units. After inspection and acceptance, they are transported to the installation site, hoisted to the base of the boiler, and then After inspection and acceptance, after installation of pipelines and other rotating machinery (blowers, induced draft fans), as well as dust removal and environmental protection facilities, trial operation can be carried out. Generally, the production unit has the boiler body in stock, so the installation period is short. Products such as WNS quick-loading gas boilers have relatively high efficiency and heat utilization rate, small footprint, long service life, and low operating costs. Generally, quick-loading furnaces are preferred for small furnaces or urgent needs. Generally speaking, the boiler from the factory to the installation and acceptance of a boiler is like this: the manufacturer makes and processes it according to the parts drawing and component drawing of the boiler drawing. Assemble the boiler assembly drawing (main installation: boiler load-bearing frame structure, upper and lower drums, water-cooled wall boiler tubes on both sides, economizer, superheater, safety devices and other pressure components), and then carry out the boiler body pressure test, qualified After that, the auxiliary equipment of the boiler (grate device, coal feeding device, slag removal device, etc.) are assembled. After each device has passed the test run, the thermal insulation construction of the boiler is carried out. In this way, the main body of the boiler is basically installed.

An industrial boiler is a device that uses the heat energy (or other heat energy) released by fuel combustion to heat the working medium to certain parameters (temperature and pressure). Boilers can be classified from different perspectives: 1. According to the structure, it can be divided into shell boiler (fire tube boiler), water tube boiler and water fire tube boiler. 2. According to different uses, it can be divided into power station boilers, industrial boilers, domestic boilers, etc. 3. According to the capacity, it can be divided into large boilers, medium boilers and small boilers. Traditionally, boilers with an evaporation rate of more than 100t/h are large boilers, boilers with an evaporation rate of 20-100t/h are medium-sized boilers, and boilers with an evaporation rate of less than 20t/h are small boilers. 4. According to the steam pressure, it can be divided into low pressure boiler (p≤2.5MPa), medium pressure boiler (2.5MP＜p≤5.9MPa), high pressure boiler (p=9.8MPa), ultra-high pressure boiler (p=13.7MPa), etc. . 5. According to the type of fuel and energy, it can be divided into coal-fired boilers, oil-fired boilers, gas-fired boilers, waste heat (waste heat) boilers, etc. 6. According to the combustion method of fuel in the boiler, it can be divided into layer burning furnace, boiling furnace and chamber burning furnace. 7. According to the flow mode of the working fluid in the evaporation system, it can be divided into natural circulation boilers, forced circulation boilers, once-through boilers, etc.

The boiler itself is a special equipment with very strict operating requirements, and natural gas is flammable, so the safe operation of gas boilers cannot be ignored. In order to ensure the safe operation of gas boilers, users must keep in mind the safety operation specifications. Yuanda Boiler will introduce the precautions for safe operation of gas boilers: 1. Explosion-proof doors must be set on the boiler body and flue to minimize the damage to the boiler caused by the explosion of the furnace; 2. Gas leakage alarm devices and ventilation equipment must be installed in the gas boiler room; 3. There must be a strict sequence control system for the start and stop of the gas boiler; the furnace and flue must be purged before ignition, and the combustible gas that may be accumulated in the furnace can be completely removed before ignition; 4. The burner must be equipped with an automatic flameout protection device; if the ignition is unsuccessful once or there is a flameout phenomenon, the burner must be able to automatically purge before re-ignition, and then the boiler can be ignited according to the normal procedure; 5. The pipelines of gas-fired boilers must be checked frequently, and there must be a necessary interlocking protection control system in the furnace; 6. The burner must be equipped with an automatic flameout protection device. If the ignition fails once or the flameout occurs, the burner must be able to automatically purge before re-ignition, and then the boiler can be ignited according to the normal procedure; 7. The most important point is that as the stoker of the gas boiler, the person in charge must conduct regular and fixed-point inspections of the gas boiler.

Gas boilers are widely used in food, printing and dyeing, chemical, pharmaceutical and other industries. As a mechanical equipment, good maintenance can prolong the life of the equipment, so you must know the name of each component, the name and location of each professional term during maintenance. Yuanda Boiler is here to help you accurately understand the heating surface of the boiler. First, let's take a look at the definition of the heating surface of the boiler: The heating surface of the boiler refers to the interface that absorbs heat from the exothermic medium and transfers it to the heating medium, including the convection heating surface and the radiation heating surface. Radiant heating surface The heating surface that absorbs heat from the heat release medium mainly by radiation heat exchange, and the heat receiving surface that absorbs heat mainly from the heat release medium by radiation heat exchange. Such as water-cooled wall tubes, furnace gallbladders, etc. Convective heating surface The heating surface that absorbs heat from the high-temperature flue gas by convection heat transfer usually refers to the heating surface that the flue gas passes through, such as flue, convection tube bundle, etc.

Softened water treatment is to change the composition and structure of sulfates and chlorides that are prone to scale in the water through physical or chemical methods, so that scale components are not easily generated during the heating and evaporation process of water, which can make the water permanent hardness. softened and lowered. We call these methods of reducing water hardness water softening. The main methods of softening water in boilers are as follows: 1. Ion exchange method: Cation exchange resin is generally used, for example, sodium ions can replace calcium and magnesium ions in water to achieve the purpose of softening. The advantages of this method are: stable water production, mature and advanced process technology, and significant softening effect, because the solubility of sodium salt is high, thus avoiding the formation of scale with the increase of temperature. 2. Membrane separation method: The reverse osmosis membrane is used, and the hardness of the water is completely reduced by the retention of the membrane. Its advantages are: the softening effect is obvious, and the treated water is suitable for a wide range. 3. Lime method: adding a certain amount of lime to the water can treat high-hardness water with a large flow, but the softening effect has certain limitations, and only preliminary softening can be done. 4. Dosing method: You can add a scale inhibitor to the water to prevent the formation of scale, make it precipitate, and then remove it.
