CHP Power Plant with 2 x CAT 1.2 MW / 50Hz Gas Generators – 2013
Complete, well maintained Combined Heat and Power plant build in year
2013 by local CAT dealer with two CAT G3516C gas engine driven
generators coupled with heat recovery systems for hot water
production. The plant was in operation till mid 2016 and currently
installed and powered. Heat recovery systems have two circuits, one
for engine jacket water and second stage of charge air cooler and
another circuit for the first stage of charge air cooler and exhaust
gas heat recovery. Exhaust gas tubular heat exchangers have exhaust
gas by-pass option. Total accumulated operating hours are 16000 and
19000 hours only. Engines has been serviced by a local CAT dealer in
accordance with maintenance manual and they haven’t had any major
breakdowns. Engine control system is standard CAT model with Siemens
logic, switchgears and step-up transformers are made by Schneider. The
building contains a separate switchgear room and a liquid storage
room. It is a lightweight construction based on a steel structure
covered with sandwich panels and inside engine room, there is
installed a noise insulation material.
