biomass gasification boiler

Biomass fired:biomass include rice husk , bagasse, mustard stalk, cotton stalk, rice husk, coffee grounds, de-oiled bran, wood chips, roasted chaff, lignite, paper sludge, coal,corn cob, spent grain and so on for a 30 ton circulating fluidized bed biomassification boiler.Biomass fired circulating fluidized bed boiler is better than other fuel in energy saving and protecting environment.

Coal-fired biomassification 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.

Obtain these honors the nation's largest gas-fired biomassification boiler lab, China's first ultra-low nitrogen boiler FGR, China's first largest shell type boilers are inseparable from the party's determination to quickly adhere to independent innovation and square fast people keep trying. China Industrial Boiler Association statistics show that side quickly clean fuel boiler annual sales amount of the first nation. Last year, the company's sales revenue grew 39%, products in short supply.

Features raw material CFB biomassification boiler technology

Comparison of biomass fuels and coal has the following characteristics: high chlorine content and the alkali metal content, volatile matter, high oxygen content and high moisture content, low fixed carbon, low ash, low calorific value, low sulfur content. The design should be performed in the boiler fuel properties.
