Abstract

A waste heat boiler (3) is connected in downstream of the fire chamber (2) and supplied with supply water (23) of which a part is removed after the water pump (25) and before the water regulating valve (26) from the water pipe (22) and directed through at least one pressure drop point (20) from where it is then supplied as cooling water (15) to the cooling channels (14). On passing through the cooling channels the cooling water is heated up to at least saturated steam temperature and is then supplied to the remote heat supply device or economiser.
