Gasification: An Alternative Process for Energy Recovery and

Gasification is a process that devolatilizes solid or liquid hydrocarbons, and converts them into a low or medium BTU gas. There are more than 100 waste gasification facilities operating or under construction around the world. Some plants have been operating commercially for more than five years. Gasification has several advantages over traditional

Sizing a Hot Water Tank Cernunnos. The first consideration is the size of the hot water tank. Obviously larger houses will have larger tanks. When selecting the size of the hot water tank, a simple rule of thumb is that for a typical domestic household, you should allow between 35 and 45 litres for every occupant.

The Boiler can be cleaned, serviced, or repaired while the thermal storage carries the heating loads. Flexibility as to when the boiler needs to be fired/stoked. When the boiler has burned out, the thermal storage can take over the job of providing heat to the system loads. This provides the operator a larger window of time for refiring.
