投資瓦斯發(fā)電可實現(xiàn)較好的收益

 

Investment in gas power generation can achieve better returns

 

瓦斯電站投資：3000-4000元/KW;機組保證連續(xù)運行功率400kW，年運行時間可達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;

 

一臺瓦斯氣發(fā)電機組年發(fā)電量：300萬kwh(消耗純瓦斯100萬立方米每年);

 

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

 

一臺瓦斯氣發(fā)電機組年發(fā)電收益：120萬元(電價按0.4元/KWh計);

 

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

 

一臺瓦斯氣發(fā)電機組年運行成本包括機油消耗、人員工資、設(shè)備維護、設(shè)備折舊等，發(fā)電成本在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.

 

一臺瓦斯氣發(fā)電機組年運行成本成本=0.10元/kWh×300萬kWh=30萬元

 

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

 

一臺瓦斯氣發(fā)電機組年收益：年收益=年發(fā)電收益-年總成本費用=120萬元-30萬元=90萬元

 

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

 

瓦斯發(fā)電站的余熱效益

 

Waste heat benefit of gas power station

 

瓦斯發(fā)電站還可采用熱電聯(lián)供系統(tǒng)，可以為煤礦提供生活用熱水，從而大限度地實現(xiàn)瓦斯的綜合利用。一臺500GF1-3RW瓦斯發(fā)電機組，排煙溫度為500℃左右，通過煙氣余熱鍋爐，吸收排煙余熱，1臺機組可產(chǎn)生354.5kg/h 壓力是0.4MPa的飽和蒸汽(飽和溫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 ℃).

 

余熱鍋爐余熱效益：

 

Waste heat benefit of waste heat boiler:

 

電站年運行時間按300天計，每噸蒸汽按70元計算。一臺瓦斯氣發(fā)電機組年可產(chǎn)生蒸汽量=354.5kg/×24h×300天。尾氣余熱效益為：2500t×70元/t≈17.5萬元。

 

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.
