Comparative analysis of the rationality of heating and heating strategy
It can be seen from the above that (heating furnace) only from the point of view of the fuel calorific value, the gas (oil) price is about 3.5 times the price of coal. The electricity price is about 9 times the price of coal. However, considering various factors, it can be seen that the operating cost of gas heating is 22.5 times that of coal burning, and the operating cost of electric heating is about 8 times that of coal burning. Each program investment comparison table program heat source level network unit boiler heat station secondary network indoor system total program plan comparison does not consider the one-time capacity increase of water, electricity and gas.
Conclusion Through the comparison of the above four heating schemes, it is indicated that at this stage China should put the development of centralized heating of coal-fired boilers (CHP) in a priority position. In remote areas where central heating is difficult to reach, gas (oil) may be appropriately used as a supplement to urban central heating. Gas heating should be used as a long-term development plan for the city. In addition, from the perspective of energy structure, China is a country with relatively poor per capita energy reserves, especially in natural gas and oil, which has a large gap compared with the world's per capita level (natural gas is equivalent to 1/30 of the world's per capita reserves). This also determines that China's energy consumption structure is dominated by coal. However, when using coal-fired boiler room for centralized heating, we must first select high-quality low-sulfur coal. At the same time, we must strengthen the heat management of regional boilers, improve thermal efficiency, improve the environment, strengthen the control of smoke exhaust and slagging, and make it as far as possible.
