How does the performance of gas boilers and coal-fired boilers compare?

Coal-fired boilers account for half of the number of boilers used in my country, while gas-fired boilers are a rising star in recent years. These two types of boilers have their own advantages and disadvantages. Let's talk about the technical experts of Zhengzhou Fangkui Boiler in terms of performance comparison.

What are the obvious differences between coal-fired and gas-fired boilers?

For coal-fired and gas-fired boilers, if these two common types of boilers are compared, the differences between them are mainly:

Difference one: Coal-fired boilers require coal ash storage sites, while gas-fired boilers do not, because the fuel is gas.

Difference 2: When the coal-fired and gas-fired boilers work normally, their water consumption is almost the same. However, the gas-fired boilers can save on auxiliary water for dust removal and slag removal.

In the gas-fired boiler room, are there any regulations on the number of furnace workers? In addition, how should the comparison be made?

There is no specific requirement on the number of furnace workers in the boiler room of gas boilers. Moreover, this type of boiler can have a high degree of automation, so it can be managed in a unified manner. Therefore, only one furnace worker is required. As for the comparison between gas-fired boilers and other boilers, a comparable standard is required, that is, only two or more types of boilers can be compared before a conclusion can be drawn.

For a gas-fired boiler, if it produces 8.6 tons of hot water, how much natural gas can be saved by raising the boiler feed water temperature by one degree? On a gas boiler, if it is 1 ton of water, then the heat required to raise the temperature by one degree is 1000 kcal, and at this time, the gas consumption can be reduced. If the calorific value of natural gas is 8600 kcal, then for the above problem, the conclusion that can be obtained by calculation is that for every 8.6 tons of hot water produced, the amount of natural gas can be saved is 1 cubic meter.
