pellet mill for biomass boiler
Biomass fuels are extremely variable in terms of heating value, moisture content, and other factors that affect combustion. Wood and most other biomass fuels are composed primarily of cellulose and moisture. As discussed previously, the high proportion of moisture is significant because it acts as a heat sink during the combustion process. The latent heat of evaporation depresses flame temperature, taking heat energy away from steam production, and contributing to the difficulty of efficiently burning biomass fuels. Cellulose, in addition to containing the chemical energy released in combustion, contains fuel-bound oxygen. This oxygen decreases the theoretical air requirements for combustion and, accordingly, the amount of nitrogen included in the products of combustion. Wood fired steam pellet mill for biomass boiler adopts three pass structure in designs to enhance heating combustion effect.
December 20, "Shanghai Air Pollution Prevention Act," a modified version of issued and published by the Shanghai Municipal People's Congress Standing Committee, with effect from January 1, 2019 came into effect.
First, the discharge of industrial waste gas or coal-fired heat production specified operating business units of toxic and hazardous air pollutants listed in the directory of institutions, central heating and other facilities to implement pollution permits management according to law shall, pursuant to the provisions of Shanghai, to the municipal or district environment department applied for and obtained the focus of air pollutants discharge Permit (hereinafter referred to as emission permits); no discharge permit shall not discharge the focus of air pollutants.
Emissions to air pollutants shall comply with the air pollutant emission standards, compliance with the total focus of air pollutant emission control requirements. New construction, expansion, renovation project focused on emissions of atmospheric pollutants, the focus should obtain the total air pollutant emission targets in accordance with the provisions of, and environmental protection examination and approval procedures for construction projects. Need to apply for a discharge permit construction projects shall obtain emission permits before being put into production as required.
Second, easy to appear in the autumn and winter of heavy pollution weather, the city of steel, building materials, coking, casting, aluminum, chemical high emission industries related company should arrange production plan to strengthen air pollution control measures. Economic information administrative departments should strengthen the guidance jointly with the municipal environment department.
Third, the environment department to determine the emissions of air pollutants key sewage units, must be configured using air pollutant emission-line monitoring equipment, and the environment departments into a unified monitoring network.
Fourth, in addition to coal-fired power plant, the city's ban on new or expanded coal burning, heavy oil, residual oil, petroleum coke, high-polluting fuel (hereinafter referred to as high-polluting fuels) facilities; the construction of coal-fired power plant in accordance with the relevant provisions of Shanghai .
Mexico 115 ton biomass fired CFB pellet mill for biomass boiler is designed on the base of our experience on circulating fluidized bed boiler.Low temperature CFB combustion technology is adopted to mix the pre-processed biomass fuel and mineral fuel.The boiler not only can reduce the operation cost,but also improve the combustion efficiency and reduce emission density of the pollution gas, such as SO, NO, etc.
Combustion effect is important to each industrial pellet mill for biomass boilers. Wood fired steam boilers is a kind of biomass fired boiler manufactured in our ZG company. Wood biomass fired steam boiler can be designed into chain grate steam boiler (stoker boiler) or CFB steam boiler with consumer’s requirement. Industrial stoker boilers and fluidized bed boilers have specific operating features with biomass fuels depending on the fuel characteristics and site requirements. Here, we suggest that according to engineers advice and industrial requirement to choose boiler type. In ZG Boiler, our advanced engineers are committed to enhance combustion effect of each industrial steam boiler.
