It peaking boiler room burns amount of natural gas:
All the other 3 months (92 days) average heat consumption is 0.16GJ/m2;
With the existing heating use gas standard (17m in Urumchi3/m2), a Heating Season can save natural gas: 3,700,000 m2×(17-10.52)m3/m2=2,398 ten thousand m3
With the existing caloric value standard (22 yuan/m in Urumchi2) increase by 370 myriametres more2, Thermal Corp can new output value: 3,700,000 m2× 22 yuan/m2=8,360 ten thousand yuan.
Government saves combustion gas subsidy:
(0.796 yuan/m2): 23,980,000 m3× 0.796 yuan/m2=1908.8 ten thousand yuan.
According to the Committee of Development and Reform of autonomous region, General Office of Finance's cogeneration of heat and power heat energy price associated documents (10.88 yuan/GJ): power plant is utilized because of unnecessary load, can increase income:
3700000 m2×0.16GJ/m2× 10.88 yuan/GJ)=644.0 ten thousand yuan.
