dual boiler coal and biomass

Coal-fired dual boiler coal and biomasss 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.

Horizontal diesel fired dual boiler coal and biomass

However, when customers purchase boilers, the fuel cost of the boiler is definitely one of the most important factors for customers. The fuel cost of a boiler includes the transportation, storage, handling and use costs of the fuel. In comparison, the cost of fuel used in oil and gas boilers is higher than that of biomass boilers and coal-fired boilers. But oil and gas boilers also have their advantages.

Wuhan Port District Social Welfare Institute (apartments for the elderly) is invested by the government pension services, with a total construction area of ​​38,000 square meters, 532 beds, mainly adopt destitute persons, social support on behalf of the elderly. Hope to provide welfare to the elderly year-round 24-hour hot water, the original dual boiler coal and biomass equipment can not meet this demand, therefore, require additional purchase orphanage hot water boiler. After much investigation, in cooperation with the welfare determined fast boiler, provides three integrally condensing gas hot water boiler (WNS1.4-1.0 / 95/70-Y.Q) by a fast boiler.
