With the rapid development of industrialization,people's living standards are improving day by day.In addition,traditional energy causes serious environmental pollution,which is not conducive to sustainable development.In their place are new clean energy sources such as solar,wind and biomass.China is a large agricultural country,with the harvest of crops,biomass straw variety and increasing year by year.Biomass straw piled up at will,wanton burning,for the environment and energy use is not the best choice.However,the high-grade utilization of biomass energy is a major advantage,pay more and more attention by the world.Biomass straw as fuel can not only replace coal,natural gas and other traditional energy,but also has the advantages of clean and renewable.Biomass straw as fuel has become a research hotspot.This article is through to the henan province large-scale use of biomass straw briquette enterprise research analysis,in henan province zhengzhou city a straw briquette fuel large-scale use of enterprise production operation mode as the research subject,the research analyzes the large-scale utilization of biomass straw briquette three links,namely the straw from the field collection and storage to the molding fuel processing and finally realizes the biomass straw briquette boiler combustion discharging standard,have summed up the biomass straw collection,storage and transport,molding fuel supply and boiler combustion emissions standard 3 big operation modes.(1)Biomass straw large-scale storage and transportation mode.The operation mode is combined with the manual centralized collection,storage and transportation mode to ensure the rapid collection of straw by taking what is needed from each other between enterprises and farmers.By modifying the common agricultural tricycle,closed transport,it reduce the loss of straw transport;With the support of the local government,a straw storage station with shelter from wind and rain and convenient transportation was established,which effectively solved the problem of large-scale collection,storage and transportation of biomass straw for straw utilization enterprises and realized the large-scale collection of biomass straw collection,storage and transportation.(2)Production and supply mode of biomass straw briquette fuel.The supply model is optimized by the heating center from the aspects of origin,type and harvest time of biomass straw raw materials to layout the molding fuel processing base.The heating center controls the information of raw material category,raw material collection amount and processing amount of fuel products in each molding fuel processing base in real time,and uniformly distributes and transports the processing amount of fuel products in each molding fuel processing base;The contradiction between the intermittent production of molding fuel and the continuous combustion of boiler is solved,and the continuous supply of molding fuel in heating center is guaranteed.(3)Operation mode of biomass straw briquette heating center.This operation mode firstly transforms the furnace structure of the original coal-fired boiler in the heating center and becomes a special burner for biomass straw briqueting fuel.Secondly,the desulphurization tower(water bath desulphurization)of the original coal-fired boiler is modified by optimizing the dedusting device,and the "one machine,one tower" and double-base desulphurization method are adopted.During the boiler combustion process,the denitrification process is added,and a cloth bag dust remover is equipped to make the dust removal system reach the three-level dust removal".The third is to add the online monitoring and control system of flue gas emission index in the process of chimney emission,which realizes the real-time online monitoring and control of various boiler emission indexes.Through the implementation of the new biomass straw scale for purchasing the transport mode,biomass straw briquette production supply and biomass straw briquette fuel heating center operating mode,scale,the collection of biomass straw raw material up to ensure the heating center forming continuous supply of fuel,combustion control,exhaust emission index efficiently after its emissions targets is far lower than the gas emission standard,implements the biomass straw briquette combustion after cleaning,environment protection,to become the real clean fuel to molding fuel.
