Hydrogen boilers The combustion of hydrogen (H2) is extremely environmentally friendly. Its combustion does not create CO2, but pure water. For all Bosch industrial boilers in the medium and large output range, we offer solutions for the use of up to hydrogen.
The amount of slag is primarily dependent on temperature and the types of coal being used and whether it is anthracite, bituminous coal, subbituminous coal, or lignite. Boilers will often slag in the upper sections of the furnace where the temperatures are higher near the superheat pendants, but slagging may also occur on the waterwalls.

2018/8/28 · There are four different types of coal: Anthracite – contains between 86% and 98% carbon by weight and it burns in boilers slowly. Bituminous – contains between 69% & 86% carbon by weight. Sub-bituminous – contains less carbon, more water and is a less efficient source of heat for boilers. Lignite – contains up to 70% water by weight.
