Products – STF BOILERS & HRSG

The boilers are drum type, natural circulation, normally with two or three vertical radiation passes. The convection pass, in which the superheaters, evaporators, and economisers are located, may be horizontal or vertical. In WTE boilers walls and superheaters sections are manufactured with Inconel cladding for corrosion protection.

Waste Heat Recovery | TLV - A Steam Specialist Company

The expelled hot gas needs to drive another turbine, so the exhaust is passed through a HRSG, which creates superheated steam that drives a downstream steam-turbine. The turbine can either drive a generator (combined cycle system) or just use the steam in process applications (cogeneration or combined heat and power (CHP)).
