Thermal heating surface unevenness is the same group, the phenomenon of unevenness in the heat load heat Boiler unevenness generated. Thermal variation caused by the structural characteristics of both, can also be caused by operating conditions of the boiler. The uneven distribution of the phenomenon of uneven speed and smoke along the width of the smoke flue temperature; serpentine planar heating surface unevenness caused by uneven pitch fumes or corridor; heating surface fouling, slagging furnace flame deflection center; run to adjust the flame so bad skewed, down, raise, etc., will cause uneven heat. (L) reaches a rated steam parameters and ensure stable operation. (2) to ensure stable ignition, combustion central appropriate, uniform distribution of the flame, the device does not burn, to avoid fouling and coke. (3) the boiler and crew safe operation under the most economical conditions.

Shandong Province is China's new energy equipment industry started earlier, more mature industrial system of provinces and cities in recent years, the overall strength of continuous improvement, a good momentum of development. 2017, the province's new energy industry added value to around 110 billion yuan. In recent years, around improve air quality and reduce consumption of coal and other fossil fuels, Shandong Province, adjust and optimize the energy structure.

Recently, Shandong Provincial Government issued "Shandong Province, the new energy industry development scale (2018-2028 years)," Planning, pointed out: will adhere to local conditions, advance planning, rational distribution, diversified development and scientific resources to promote biomass as energy recycling and clean use. In the northwest, Shandong medium straw-rich areas in the construction of straw-based biomass power generation projects; gathering area in Lunan wood processing and straw-rich regions in the construction of agricultural and forestry biomass power generation projects; fruit tree branches in Shandong Peninsula firewood resource-rich regions, temperatures promote urban domestic garbage power generation project. In the industrial wastewater mailing harmless treatment concentrated areas and livestock scale farming areas, rational distribution of biogas power generation project. And strive to 2022, the province of biomass power generation capacity of around 3.5 million kilowatts; by 2028, the province's biomass power generation installed capacity reached 500 million kilowatts. The plan also proposed to play the advantages of Shandong Province as the province of biomass resources, focus on breakthrough high efficiency and low nitrogen biomass combustion, gasification coupled power generation, cellulosic ethanol, biomass aviation fuel, biomass olefins, biomass and other biomass graphene energy thermal conversion and biochemical transformation and other key technologies, key equipment focus on promoting biomass boilers (kilns), briquette, power generation equipment, advanced gasification, carbonization, in areas such as biological fermentation research and development and industrialization, a series products and scale production capacity, cultivate material and equipment manufacturing, high-value product development, integrated services group of students and other characteristics of key enterprises, and strive to build a diversified use of biomass demonstration provinces. 2022, the province's biomass energy industry output value and strive to exceed 40 billion yuan; to 2028, the province's biomass energy industry output value and strive to reach 600 billion yuan.

How do you calculate the amount of fuel required for a boiler? To know the amount of fuel required for a boiler, it is necessary to first determine the boiler's specifications and steam production, and calculate the actual enthalpy increment of the boiler according to its steam pressure and steam output, and then calculate the heat required according to the boiler's efficiency. Or the amount of heat that fuel can provide. Then through the fuel calorific value to calculate the amount of fuel required for the boiler, and get the specific value.

Use of fan on boiler

The boiler is a kind of machine that uses coal to supply heat energy, so the boiler should use ventilator in the process of using it. Today we will talk about the role of the ventilator in the boiler.
