生物質氣化發電技能是指生物質在氣化爐中轉化為氣體燃料,經凈化后直接進入燃氣機中焚燒發電或進入燃料電池發電。氣化發電的關鍵技能之一是燃氣凈化,經氣化得到的燃氣都含一定的雜質如:灰分、焦炭和焦油等。需通過凈化體系把雜質除掉,以確保發電設備的正常運轉。
D88尊龙Biomass gasification power generation technology refers to biomass in the gasifier into gas fuel, after purification, directly into the gas engine burning, power generation or into the fuel cell power generation. One of the key skills of gasification power generation gas purification, gas was obtained with certain impurities such as ash, coke and tar etc.. Impurities must be removed through the purification system to ensure the normal operation of the power generation equipment.

生物質氣化發電可分為內焚燒機發電、然汽輪機發電、燃氣-蒸汽聯合循環發電體系發電和燃料電池發電體系發電等。內燃機通常需要在柴油機或然氣機的基礎上進行改造,以適應生物質燃氣熱值較低的特點;燃氣輪機適用于焚燒高雜質、低熱值而且規劃較大的生物質燃氣;燃氣-蒸汽聯合循環發電體系能夠進步提高發電功率;燃料電池發電是在一定條件下使燃料和氧化劑發作化學反應,將化學能轉換為電能和熱能的進程,燃料電池本體的發電功率高,熱電聯產的總熱功率可達80%以上。
Biomass gasification power generation can be divided into internal combustion generator power generation, natural gas turbine power generation, gas steam combined cycle power generation system, power generation and fuel cell power generation system. The internal combustion engine is usually required in the transformation of the diesel engine based on contingent gas machine, in order to adapt to the characteristics of biomass of low calorific value gas; gas turbine is suitable for burning low calorific value, high impurity and planning large biomass gas; gas - steam combined cycle power generation system can improve the step power; fuel cell power generation is to make fuel and oxidizer agent under the condition of certain chemical reactiongenerate to convert chemical energy into electricity and heat process, power generation of the fuel cell body is high, the total thermal power cogeneration can reach more than 80%.
