Released by the heating device (burner) heat transfer by radiation is first absorbed waterwall waterwall Boiling water, a large amount of steam into the drum for water separation (excluding DC furnace), separated saturated steam enters the superheater , and it continues to absorb the top horizontal flue furnace by radiation, convection, heat of the flue gas flue of the tail, and the superheated steam to reach the required operating temperature. Power generation boilers are generally provided with a reheater, it is used to heat the steam through the high pressure cylinders acting reheater go out of the reheat steam, the low pressure cylinder to continue to generate power. Popular terms, the steam boiler in korea is to absorb combustion heat of the fuel into the water some parameters (such as pressure, temperature, etc.) of the steam device. Boilers and boiler furnace divided into two parts, the pot is filled with water to a metal container, partially combusted fuel furnace, the heat absorption of the water inside the pot furnace fuel combustion converted to steam, with the basic principles of almost boiling water, the pot equivalent kettle, oven stove equivalent. 1, by fuel, our existing steam boiler fuel that can be used are: gas boilers, coal-fired boiler, oil-fired boiler, electric heating boilers, nuclear boilers, waste heat boiler, etc., of which the first four of the most common.
As the "Star Pavilion" on the show, the arrival of fast boiler is attracted quite a stir. Guests and friends from all over the world friends are gathered in front of "fast Boiler" booth, feeling the charm to bring clean boiler. This is the third appearance in the fast side of the trade show, our booth set up in the middle of the field, in the light against the background, beautiful booth set off for the scene of different merchants brought extraordinary appeal.
Coal-fired boilers to gas boilers benefits and precautions With the rapid development of national energy-saving environmental protection, the traditional coal-fired boiler can not meet the needs of the times. Therefore, the coal-fired boiler biomass boiler or gas boiler has become in many boiler user's choice. Before the transformation, to understand the difference between .1 and gas boiler fired boiler. Circulating fluidized bed combustion boiler fired by coal crushing device fluidized combustion process, the coal by crushing device percutaneously into the bunker through a the spreading coal coal injecting air into the furnace; circulating ash by heating, fluidized combustion process. When the coal into a gas fuel is injected directly into the combustor for combustion. 2. Combustion of Coal is mainly composed of C, H, O, N, S, ash and moisture and other elements. Generated when coal SO2, SO3, NOx ash and moisture, and SO2, SO3, NOx from flue gas emitted into the atmosphere, pollute the environment and cause harm to humans. The main components of the exhaust gas and coke are CO and H2. The main produce CO2 and H2 post-combustion, much lower than coal-fired boiler SO2, SO3 and NOX emissions. 3. Ventilation pressurized combustion coal combustion boiler used in a combustion mode. The bottom of the combustion process through the induced draft fan with fan and completed. In the combustion of coal, it requires a lot of air. Gas under a slight positive pressure in the boiler or burner slightly negative pressure, which requires less airflow. Burner air may be pre-mixed with natural gas. 4. coal boiler control reasons, material thickness, amount of wind, the wind volume, wind and other than coal, coal-fired boiler is difficult to automatically adjust the operating parameters of the boiler according to the load. However, fewer factors gas boiler, the burner valve can be adjusted according to the size of the load, easy to implement automatic control. Coal-fired boiler to a gas boiler Notes: Main results are as follows: (1) small boiler, the coal-fired boiler to a gas boiler, i.e. the negative pressure of combustion from the original to the current combustion slight positive pressure, and must pay attention to the furnace wall structure sealing problems. Closely related (2) selection and arrangement of the burner and furnace, the degree of filling of the flame in the furnace is preferably not formed dead air, to avoid the interference of adjacent flame burners, to avoid interference from adjacent burner flame. Unburned gas - air mixture should not be in contact with a heated surface, in order to avoid incomplete combustion. Gas combustion. Gas burner arrangement disposed conduit and ducts should be considered reasonable gas pipe and duct arrangement, ease of operation, inspection and maintenance. (3) the transformation of coal-fired boilers is mechanized layered gas boiler should be removed before the arch and the arch, and the bottom heating surface increases, in place of the grate, the grate to prevent overheating. Gas Velocity (4) on heat transfer surface of the fly ash is not restricted abrasion conditions, convection heating surface heat transfer coefficient is increased, increasing the pressure in the boiler where H is unduly increased. Boiler erosion surface. At this time, the capacity of the boiler should be noted that the steam separator to ensure the quality of the steam.
Works chemical plant boilers is what works what chemical plant boiler is? Energy conversion device is a boiler, a boiler input energy comprises a chemical energy, electrical energy, thermal energy of the flue gas temperature and the like. After conversion of the boiler, steam, water or high-temperature organic heat carrier having a certain thermal energy to the boiler outlet. Mainly used in thermal power plants, ships, locomotives, industrial and mining enterprises. The main principle is a use of the chemical energy released by combustion of boiler fuel or industrial waste heat transferred to the water container, the water reaches the desired temperature or pressure of the steam heating apparatus. Boilers and boiler furnace two parts at the same time, water enters the boiler, the boiler heating surface in the steam - water system will absorb heat transferred to the water, so that by the hot water reaches a certain temperature and pressure to produce hot water or steam or, is introduced into the application. cation. In the combustion apparatus part, sustained release heat of fuel combustion, high temperature flue gas produced by combustion heat propagation, to transfer heat to the boiler heating surface, the temperature itself is gradually reduced and finally discharged through a chimney. Works chemical plant boilers is what - Classification steam boiler in korea: First, the fuel can be divided into: 1, coal-fired boilers, 2, oil-fired boiler, 3, gas boiler, 4 electric boiler, boiler and nuclear 5, 6, waste heat boiler, etc., most top four, the most common, the lowest operating costs of coal-fired boilers, but a large area, serious environmental pollution, the requirements of operators, gas boilers high degree of automation, operating costs than coal, accounting small land area, requiring fewer operators, I did not use electric boiler, but running costs should be the highest, but the small boiler footprint, environmental protection is the best, the other boiler is not introduced, because I do not understand you the meaning of. two. The heat transfer mode can be divided into water-tube boilers, the thermocouple tube boiler, water tube boilers and fire tube boiler. Usually gas fuel boiler fire tube boiler, typical Type: series WNS (horizontal combustion boiler combustion chamber), this boiler characteristics: simple structure, the rated capacity of the evaporator is generally small (typically 10 tons or less, have a greater , but generally not more than 35 tonnes), starting the furnace pressure faster, lower quality requirements boiler; coal-fired boilers typically water boiler. Tube boiler, water tube boiler high thermal efficiency, but the complex structure of the boiler a higher quality requirements.
