biomass waste fuel wheat dry matter boiler
Coal-fired biomass waste fuel wheat dry matter 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.
Factors such as the way in which fuel is obtained, the cost of acquisition, and the cost of transportation also affect the cost of fuel. When the biomass waste fuel wheat dry matter boiler uses different fuels, there will be other inputs. Where biomass boilers and coal-fired boilers have fuel storage, coal-fired boilers generally need to be equipped with coal crushers and coal feeders.
How much gas 6 tons per hour of steam biomass waste fuel wheat dry matter boilers need? How much natural gas steam boiler needs an hour? 6 tons calorific gas steam boiler 360 million cards, the design pressure of 1.25MPa, the maximum steam temperature 194 degrees, consumption of natural gas per hour at full load boiler 420m3. The above data is only theoretical gas consumption, the actual gas consumption is influenced by many factors. 1, the thermal efficiency of the design; 2, insulation effect; 3, discharge times; 4, fireman professional level; gas and steam boilers are mainstream industrial production equipment. Especially since the implementation of the national coal gas policy, China has not yet biomass boilers and coal-fired boilers appear. Users select the gas-fired most important criteria are reasonably priced, low operating cost, easy to say and difficult choices. What price is only worth buying for key boiler, gas boiler selection is a measure of its quality, how to identify the quality of the boiler? 1, should be sufficient energy, emissions, low emissions; 2, low air consumption; 3, low operating costs; 4, stable; 5, long life; condensing gas boiler advanced design, for flue gas flow reasonable the design optimization. Sufficient heat transfer through the flue gas and smoke tubes economizer, heat the fuel sufficiently. Gas boiler for maximum energy efficiency.
State all the more attention to environmental protection, to provide more excellent atmosphere, we respond positively to the country's environmental protection, promote the biomass waste fuel wheat dry matter boiler from coal to gas project. Among the many boiler suppliers, we chose the fast boiler. First, the party quickly done very well in terms of cleaning the boiler, the second is fast side also very comprehensive after-sales involved. The optional gas boiler was used after running fully meet the needs of our pharmaceutical production, both energy-saving and environmental protection, but also a very high thermal efficiency, saved us a lot of fuel costs. --customer feedback
