Feasibility And Effect Study Of Boiler Energy-Saving Technology On Biomass Pellet Fuel Instead Of Coal

Economic growth accompanied by an increasingly serious environmental problems,from the decision of seven ministries,growing national emphasis on energy-saving emission reduction,especially for the out and small boiler shutdown integration.Long Yan City Government in response to the national call to encourage promotion of electricity,natural gas,liquefied petroleum gas,biomass fuels,such as coal,coal-water slurry and washing clean energy,to eliminate the industrial boiler update.Application of biomass fuels plays an invaluable role on the environment and social values.Biomass briquette with ordinary biofuels(straw,wood chips,etc)has a great advantage over,forming greater packing density of biomass fuels not only solved the transportation problem of fuel,and are critical to the stability of combustion of fuel.This paper takes the DZL4-1.25-W ? boiler of a certain enterprise in Fujian as an example,and the boiler's energy saving and emission reduction is reformed.The paper focuses on the following aspects of the relevant research:(1)Firstly,through detailed investigation and analysis of the development potentiality of biomass resources in Fujian province,the combustion characteristics of biomass fuel are discussed,and the quality and supply of biomass fuels in Fujian province are analyzed,and it is feasible to change the fuel of coal-fired industrial boilers to burn biomass fuels in Fujian province.(2)Secondly,the paper analyzes the various problems existed in the original coal-fired industrial boiler,according to the original boiler in feeding mechanism,the front and rear arch configuration,the ventilation mode and the secondary wind system,the problem of ash removing slag device,and combining with the actual situation,the combustion characteristics of biomass particles fuel and the original boiler combustion of biomass particles fuel easy to advance fire after the problem,proposed a targeted renovation program.(3)Participate in the DZL4-1.25-W ? boiler's concrete reformation plan design and construction process of a certain enterprise in Longyan city of Fujian,the fuel feed rate control,boiler feeding device,and Arch,air distribution is modified.According to the transformation of energy efficiency before and after the test results confirmed the energy saving achieved the expected goals.(4)Combining with the concrete problems of the boiler renovation,the author puts forward his own views on the reform and safety operation of the boiler.
