生物质秸秆发电的优势有哪些?

返回 2021.02.26 来源:http://www.huannengpower.com
秸秆发电是秸秆优化利用的主要形式之一,是生物质气发电的一种,秸秆是一种很好的清洁可再生能源,每两吨秸秆的热值相当于一吨标准煤,而且其平均含硫量只有千分之3.8,而煤的平均含硫量达到百分之一,在生物质的再生利用过程中,排放的CO2与生物质再生时吸收的CO2达到平衡,具有CO2零排放的作用,对缓解和更终解决温室效应问题将具有重大意义。
Straw power generation is one of the main ways to optimize the utilization of straw, and it is a kind of biomass gas power generation. Straw is a good clean and renewable energy. The calorific value of every two tons of straw is equivalent to one ton of standard coal, and its average sulfur content is only 3.8%, while the average sulfur content of coal is up to 1%. In the process of biomass recycling, the emission of CO2 is closely related to biomass regeneration It is of great significance to alleviate and ultimately solve the problem of greenhouse effect.
秸秆发电一般分为燃料准备阶段和输送阶段,进入燃料仓之前的秸秆处理生产线为燃料准备阶段,从燃料仓到炉前这个阶段为燃料输送阶段。
Straw power generation is generally divided into fuel preparation stage and conveying stage. The straw treatment production line before entering the fuel bunker is the fuel preparation stage, and the stage from the fuel bunker to the furnace is the fuel conveying stage.

1、燃料准备阶段的工艺流程
1. Process flow in fuel preparation stage
秸秆通过皮带输送线(上料)->切碎机(粗加工)->锤磨机(细加工)->旋风分离器(分离切碎的秸秆和粉尘,秸秆进入料仓)->布袋除尘器(粉尘回收,气体排放)
Straw through the belt conveyor line (feeding) - > chopper (rough processing) - > hammer mill (fine processing) - > cyclone separator (separation of chopped straw and dust, straw into the bin) - > bag filter (dust recovery, gas emission)
2、燃料输送阶段的工艺流程
2. Process flow of fuel delivery stage
秸秆通过位于燃料仓下部平面布置的由变频电机驱动的横向排放螺旋输送机驱动进而送入一个纵向螺旋输送机。从纵向螺旋输送机出来的燃料进入出料口的螺旋气阀。通过一次风机将从位于燃料仓的下部出料口的燃料以气动的形式分别送入燃烧器进行燃烧。
The straw is driven by a transverse discharge screw conveyor driven by a frequency conversion motor, which is arranged in the lower plane of the fuel bunker, and then sent to a longitudinal screw conveyor. The fuel from the longitudinal screw conveyor enters the screw valve at the discharge port. Through the primary air fan, the fuel from the lower outlet of the fuel bunker is pneumatically sent to the burner for combustion.
