Oil boilers and gas boilers have the advantage of relatively high thermal efficiency and control of oil injection or gas supply to maintain a constant combustion state, which makes the maintenance and management of the boiler convenient, but has the disadvantage of high fuel costs.

The firewood boiler uses heat generated by burning firewood (wood, wood, waste wood, etc.), but its structure is simple and the fuel cost is very low.However, the thermal efficiency is relatively low and the fuel must be continuously supplied. The disadvantage is that it needs to be checked at any time.

Therefore, in recent years, a hybrid boiler of an oil boiler (or gas boiler) and a coal fired boiler has been developed. However, the conventional hybrid boiler has a disadvantage in that its size is too large because it simply integrates two types of boilers into one boiler.
