Our customers here will choose coal-fired atmospheric gas boilers, which are cheap and easy to use. If local coal burning is not allowed, a granular boiler can be used, which will lower the later cost.

I can give you the calorific value of various fuels. You can refer to the local fuel price and calculate it yourself.

The calorific value of one kilogram of coal is about 6000 calories.

The calorific value of gas is about 1 1000 kcal.

Natural gas is about 8800 calories per cubic meter.

Electricity is 860 kcal per kWh.

The calorific value of particles is generally around 4000 calories.

Boiler price is also the cheapest of coal. If there is a gas pipeline, there is no need to add a gasifier, and the price should be similar to that of particles.
