Why does natural gas have an advantage over coal in heating, but an obvious disadvantage in power generation?

Natural gas heating is used to solve the pollution problem of urban coal-fired heating to the surrounding environment. Compared with China's coal resources, natural gas resources are unevenly distributed, and the main gas sources are concentrated in Xinjiang, Sichuan and Shaanxi. If natural gas is exported to generate electricity, it will face high pipeline construction costs. If electricity is generated in gas source, it will increase the cost of long-distance transmission.

because of its very high heat ratio, natural gas has an advantage over coal in heating efficiency. But at the same time, the price is much better than coal, which will greatly increase the cost of power generation. In addition, transportation is not as convenient as coal, so there will be obvious disadvantages. Natural gas has more advantages than coal in work because it is cleaner. And it won't take up more space. However, power generation also has obvious disadvantages, because the heat of the weather is not as high as that of coal, so the disadvantages of power generation are more obvious.

natural gas is superior to coal in industry because of its high heat. The obvious disadvantage of power generation is poor energy conversion ability. Why is natural gas superior to coal in heating? Because it is a natural substance and oil, its heat is much faster than that without it. Therefore, it is generally better to use natural gas, but the cost is higher.

this shows that when the price of natural gas is compared with the price of coal, natural gas is better than coal before it can generate the same electricity! In other words, natural gas may consume more natural gas. In this case, it is a disadvantage, and then coal generates electricity. But there is also a lot of room for development.

natural gas has advantages over coal in heating. It is more polluted than coal, which can comprehensively utilize energy, but natural gas cannot be comprehensively utilized, and the price is relatively high. Besides the calorific value of natural gas is higher than that of coal, the air pollutants emitted in the combustion process are far lower than that of coal. Natural gas is not only superior to coal in heating, but also has the advantages of less investment and less pollution in power generation. The main disadvantage is that the supply of natural gas is often in a bottleneck state, and the price of natural gas is getting higher and higher.

Because natural gas itself is the first choice for small-area heating, the price is more economical, and the heat dissipation mode is different from that of coal, which is in a dispersed state; Coal is suitable for large-scale heating, such as power generation. Natural gas is more energy-saving and environmentally friendly, suitable for household use. Natural gas is superior to coal in heating, mainly because of its high calorific value and relatively small pollution; The disadvantage of power generation is mainly due to the relatively large power generation!

Mitsubishi et al. It seems that China Aviation Engine Group is the only domestic brand that is really designed and produced by itself. The main products are qd2, qd7, QD128, qd185 and other units. It seems that Aviation Power (Beijing) Energy Holding Co., Ltd. is building a natural gas distributed energy station for domestic gas turbines.
