2020 Hot Sale New Type DZH Biomass Fired Steam Boiler
The advantages and disadvantages of natural gas and biomass 2020 hot sale new type dzh biomass fired steam boiler steam boiler 1, the price of biomass fuels is greatly affected by seasonal. If the biomass supply is the best, the best option is to choose natural gas. 2, gas pipeline need to connect gas-fired, gas-fired gas pipelines can not be used. 3, the storage of the biomass fuel is more cumbersome than natural gas. 4, biomass boilers are not available in all areas, need to be combined with local boiler policies.
Fangkuai Group has more than 60 independent intellectual property rights, advanced clean fuel boiler manufacturing technology, and jointly established a clean fuel boiler production, research and research cooperation base with Tsinghua University and Xi'an Jiaotong University. An enterprise with a R & D and test center for clean fuel boilers. The thermal efficiency of “Fangkuai” boilers can reach 107%, which has been included in the national special equipment energy-saving catalog. The company developed ultra-low nitrogen full premixed combustion condensing boilers and ultra low nitrogen emission fuel gas boilers, which are developed by the company using Ultran condensation technology.
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.
Biomass fired 2020 hot sale new type dzh biomass fired steam boiler combustion process
The biomass fuel is fed into the furnace screw feeder, where due to the high temperature flue gas and the role of the primary air gradually preheating, drying, fire, burning, this process a large number of volatile precipitation, burn vigorously. After the resulting erosion main heating surface temperature flue gas boiler, the boiler economizer heating surface of the tail and air preheater, and then into the dust, and finally through the chimney into the atmosphere. Not gasified fuel side to the rear of the grate movement until burnout, the last remaining small amount of ash fall behind the grate slag mouth.
