Waste to energy (WTE) systems for district heating

Jan 01, 2013 · Boilers for waste facilities are drum-type boilers, which are characterized by a drum (and by being below the critical steam pressure of 221 bar). The drum is a large high-pressure cylinder containing water situated at the top of the boiler, which physically separates water evaporation from where the steam is superheated.
