Which is better when coal is changed to electricity and coal is changed to gas

This winter Hebei Province issued an early warning of natural gas supply orange, "News Live Room" to analyze how to ensure the heating and environmental protection department issued a special notice and the CCTV "news 1+1", Beijing issued urgent notice to start coal-fired unit heating, the Ministry of housing construction department issued the Ministry of housing emergency notice to accelerate the solution of the current heating process This indicates that this restriction on natural gas consumption is not a partial phenomenon.

Why should coal be converted to gas instead of coal instead of electricity, since natural gas is so tight?

1. In terms of environmental protection

In terms of environmental protection, natural gas is indeed more environmentally friendly than electricity.

Because China is a large coal country, power generation relies mainly on coal-fired power generation, and the supply of other wind and hydro power is limited.

If electricity can rely on coal, it will be more polluted.

In terms of environmental protection, coal to gas is a bit better.

But don't forget that coal burning is still a lot of environmental protection compared to the residents directly burning coal, because civilian coal burning will not do dust removal, desulfurization and other environmental protection measures, but the environmental protection measures of thermal power plants are in place, so the promotion of electric heating can also effectively reduce environmental pollution.

2. From resource reserves

China's rich coal is short of oil and gas, and natural gas is mainly dependent on imports. Insufficient supply of gas will probably become the norm in the future.

But coal is rich, and coal power generation can be supplied for a long time.

In terms of resource reserves, coal to electricity is stronger than coal to gas.

3. From the price point of view

The heating cost of natural gas is about 3, 4 times the cost of burning coal for heating gas in the past, and the price is too high for rural areas. The main reason is that the price of natural gas is rising.

The cost of coal to electricity is much more expensive than coal burning.

However, due to the emergence of mature electric heating equipment and air heat pumps, the electricity consumption is still lower than that of natural gas after the cost is reduced.

In terms of price, coal to electricity is stronger than coal to gas.

4. From the difficulty of construction

Our country has a mature power grid system, which is ready-made, and coal can be changed to electricity only by installing electric heating equipment.

In addition to installing the wall hung furnace, the coal to gas needs to install various gas supply pipelines. The construction is very difficult.

In terms of construction difficulty, coal to electricity is stronger than coal to gas.

5. From the security point of view

Our country has a mature power grid system. The safe use of electricity is the consensus of the whole people. The basic knowledge of electricity is universal, and the construction of power supply safety is also in place.

But natural gas is not the same, natural gas is flammable gas, after leakage, it is easy to explode, and the present rural natural gas is all the pipe pipe hypothesis, there is a certain risk of safety.

In terms of safety, coal to electricity is stronger than coal to gas.

6. Economically

The two energy sources are the same in both pipes and terminal radiators, both in natural gas or electric energy, so there is no comparability between the pipes and the terminal radiators. The only difference is that the furnace is different.

The main equipment used for natural gas heating is hanging wall furnace. Although the wall hanging furnace is also divided into electricity and natural gas, most of them are mainly natural gas. It is mainly through the combustion of natural gas to heat the water and send it to the radiator to achieve the purpose of heating. The main equipment used for electricity is air source heat pump, which is also used to heat water and send it to radiator or ground heating pipe. The principles of both work are basically the same.

A cubic natural gas is equal to the power of 9.88KW. The thermal efficiency of natural gas is generally 85% (with the loss of smoke heat and combustion efficiency). 1 cubic natural gas can produce 8500 calories, and 860 calories can be generated by 1 degrees. We first take 1 cubic natural gas as the standard.

A cubic natural gas (generating 8500 calories), about 2.5 yuan (because the price is different, and there is a ladder type growth, specific reference). Electric energy temporarily does not count the heat loss, the effective heat of 8500 big cards is equivalent to the power consumption 10.1 degrees, according to the electricity price of 0.52, cost 5.3 yuan, if added heat loss, will be more. One cubic natural gas (price 2.5 yuan) =10.1 kilowatt power (price 5.3 yuan)

This shows that natural gas is more economical and saves more than half of electricity. Is this a surprise?

Therefore, even under the "gas shortage" environment, the majority of users still insist on using natural gas, heating or cooking and bathing are much more economical than electricity consumption. In order to save more, Jiuding radiator suggests that it can purchase heat radiator with high heat sink and high efficiency, such as Jiuding copper and aluminum composite radiator, high quality electrolytic copper corrosion and heat conduction fast, large waterway is not easy to block, aviation grade aluminum profile radiator is fast, large aluminum fin convective diversion effect is good.
