K. Sipilä, in Advanced District Heating and Cooling (DHC) Systems, 2016 3.6.1.6 Gas cooling. In the gasification of solid REF, impurities that cause boiler corrosion are transferred to the product gas. Therefore, the product gas is cooled from 900 °C to about 400 °C so that materials causing corrosion, such as alkali chlorides, turn from gas into solid particles.

Question: (a) Dry saturated steam at a temperature of 180ºC is to be produced in a fire tube boiler from the cooling of 50 000 kg h–1 of flue gases from a pressurised combustion process. The gases enter the tubes of the boiler at 1600ºC and leave at 200ºC. The feed water is externally preheated to 180ºC before entering the boiler.
