投资瓦斯发电可实现较好的收益

 

Investment in gas power generation can achieve better returns

 

瓦斯电站投资：3000-4000元/KW;机组保证连续运行功率400kW，年运行时间可达300天以上;

 

Investment of gas power station: 3000-4000 yuan / kW; the unit can guarantee continuous operation power of 400KW, and the annual operation time can reach more than 300 days;

 

一台瓦斯气发电机组年发电量：300万kwh(消耗纯瓦斯100万立方米每年);

 

Annual power generation of a gas generator unit: 3 million kWh (consumption of 1 million cubic meters of pure gas per year);

 

一台瓦斯气发电机组年发电收益：120万元(电价按0.4元/KWh计);

 

Annual power generation income of one gas generator unit: 1.2 million yuan (electricity price is calculated as 0.4 yuan / kWh);

 

一台瓦斯气发电机组年运行成本包括机油消耗、人员工资、设备维护、设备折旧等，发电成本在0.10元/kWh左右。

 

The annual operation cost of a gas generator unit includes oil consumption, personnel wages, equipment maintenance, equipment depreciation, etc., and the power generation cost is about 0.10 yuan / kWh.

 

一台瓦斯气发电机组年运行成本成本=0.10元/kWh×300万kWh=30万元

 

The annual operation cost of a gas generator set = 0.10 yuan / kWh × 3 million kwh = 300000 yuan

 

一台瓦斯气发电机组年收益：年收益=年发电收益-年总成本费用=120万元-30万元=90万元

 

Annual income of a gas generator unit: annual income = annual power generation income - annual total cost = 1.2 million yuan - 300000 yuan = 900000 yuan

 

瓦斯发电站的余热效益

 

Waste heat benefit of gas power station

 

瓦斯发电站还可采用热电联供系统，可以为煤矿提供生活用热水，从而大限度地实现瓦斯的综合利用。一台500GF1-3RW瓦斯发电机组，排烟温度为500℃左右，通过烟气余热锅炉，吸收排烟余热，1台机组可产生354.5kg/h 压力是0.4MPa的饱和蒸汽(饱和温133℃)。

 

The gas power station can also adopt the combined heat and power system, which can provide domestic hot water for coal mines, so as to realize the comprehensive utilization of gas to a large extent. A 500gf1-3rw gas generator set, the exhaust gas temperature is about 500 ℃, through the flue gas waste heat boiler to absorb the exhaust heat, one unit can produce 354.5kg/h saturated steam with pressure of 0.4MPa (saturation temperature of 133 ℃).

 

余热锅炉余热效益：

 

Waste heat benefit of waste heat boiler:

 

电站年运行时间按300天计，每吨蒸汽按70元计算。一台瓦斯气发电机组年可产生蒸汽量=354.5kg/×24h×300天。尾气余热效益为：2500t×70元/t≈17.5万元。

 

The annual operation time of the power station is calculated as 300 days and 70 yuan per ton of steam. The annual steam generation capacity of a gas generator unit is 354.5kg/24h × 300D. The waste heat benefit of tail gas is 2500t × 70 yuan / T ≈ 175000 yuan.
