Efficient Gasification – The Log Boiler

When we control that environment we measure exhaust temperature and we match that exhaust temperature with our incoming air. We can hold our exhaust temperature where we want it +/-5 degrees set it at the right temperature we get out internal temperature where we need it and the gasification takes place so we don’t go out of gasification.

Exhaust Gas Steam Boiler

A turbocharger recover some of it, but there is still heat losses that can be recovered by means of an Exhaust Gas Boiler, EGB. Utilization of the energy in the exhaust gas is restricted due to risk of low temperature corrosion on the gas side of the tubes. The
