This energy efficient counter current design also results in a relatively low 0.54 oxygen/dry coal mass ratio. The water/dry coal mass ratio was 0.40. Steam was 81 of the water feed and the balance was moisture in the feed. In another study 6 the same coal was gasified using a Shell gasifier. This is a high temperature entrained flow design.

Boiler Efficiency Kane International Limited

Boiler Efficiency. The objective of a boiler is to burn the hydrogen contained in the fuel with oxygen from the atmosphere to produce heat. Combustion efficiency analysers exploit the fact that by knowing the fuel (and its chemical composition) and measuring the flue gas temperature and either the oxygen or carbon dioxide level the efficiency of the boiler can be calculated.

How to Run a Coal Fired Boiler at the Best Efficiency

Pulverized coal fired boilers the total losses account to about 12 to 14 . Roughly 50 of the losses can be tuned to the optimum and the other 50 is governed by fuel properties like hydrogen in fuel moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.
