發(fā)布時間:2019-04-04 09:03
【摘要】:本研究以某公司30 k W微型燃機為對象,利用仿真模擬的方法,研究其以稻草氣、棉柴氣、木片氣和沼氣4種生物質氣為燃料的可行性,計算燃用不同生物質氣時微型燃機的安全運行工況。研究表明:該燃機無法燃用熱值較低的稻草氣與棉柴氣,因其無法同時滿足壓氣機喘振裕度及透平入口溫度的要求;燃用熱值較高的木片氣和沼氣時,微型燃機可以安全運行,木片氣可以在壓比為3.247~3.251、功率為18.13~32 k W范圍內安全運行,沼氣可以在壓比為3.203~3.207、功率為15.9~32 k W范圍內安全運行。針對微型燃機無法燃用低熱值燃料這一問題,提出改進壓氣機方案,該方案增大了燃用低熱值燃料時壓氣機的喘振裕度及透平入口溫度,使其能夠安全運行。
[Abstract]:In this paper, the feasibility of using straw gas, cotton wood gas, wood chip gas and biogas as fuel was studied by means of simulation and simulation for a 30kW micro-gas turbine in a certain company, and the feasibility of using straw gas, cotton wood gas, wood chip gas and biogas as fuel was studied. The safe operation condition of micro gas turbine with different biomass gas is calculated. The results show that straw gas and cotton wood gas with lower calorific value can not be used in this gas turbine because it can not meet the requirements of compressor surge margin and turbine inlet temperature at the same time. When burning wood chip gas and biogas with high calorific value, the micro gas turbine can operate safely. The chip gas can operate safely in the pressure ratio of 3.247 ~ 3.251 and the power of 18.13 ~ 32 kW. The biogas can be operated at a pressure ratio of 3.203 ~ 3.207, and the gas can be operated safely at a pressure ratio of 3.247 ~ 3.251 and a power of 18.13 ~ 32 kW. The power is within the range of 15.9 and 32 kW safe operation. In view of the problem that low calorific value fuel can not be used in micro gas turbine, an improved compressor scheme is proposed, which increases the surge margin and turbine inlet temperature of the compressor when low calorific value fuel is used, so that the compressor can operate safely.
