There are many different types of burner in use now for various purposes and in various areas, depending on the supply of fuel and the purpose of the burner. In Europe, the gas burner has become very common in the lower-powered section, which is not to say that there are no large gas burners on the market!
The oil burner is also very common, ranging from the extra light oil that is common in countries with low temperatures to the heavy oil burners used in some industrial processes. Oil burners will be in use permanently for many reasons.
A coal burner is common in industry and for power stations, naturally enough, especially in countries with reserves of coal! Again, coal is not always coal and there are many different varieties and qualities in use. Coal burners have a bad reputation for dirt and pollution, which is not always justified.
Wood burners were once only to be found in the household, but now a wood burner may be used in large-scale operations. The wood burner is also popular since this is a renewable source of energy and sometimes receives subsidies for this reason.
In the petrochemical industry it is very common to find a process gas burner. This uses the waste gas produced b the cracking procedure and utilises it for powering the reheaters and other equipment.
