Cold Climate Heating and Power - New Coal Fired Boiler Using Indeck Travagrate® Stoker

travelgateIndeck Keystone Energy was awarded a contract for the supply of two superheated 120,000 PPH / 600 PSIG Coal Fired boilers with auxiliary equipment for field erection. These systems will be installed for central heat and power at a subarctic climate location in North America . The boilers are being furnished in two phases in order to replace existing 1950's units without impeding the heating requirements of the plant.

solid-fuelIndeck is using its time tested and proven Travagrate® stoker with reciprocating feeders and over fire air and ash re-inject system for lower emissions and increased efficiency. The stoker is completely assembled and match marked prior to disassembly to help the field to reassemble. Feeders and stoker drive unit are fabricated, assembled and tested prior to shipment. This is all done in our shop in Erie, PA.


Coal Fired Boiler For Heating Plant

Indeck Keystone Energy was awarded a contract for the supply of an 80,000 PPH / 750 PSIG stoker fired coal boiler with auxiliary equipment for field erection. The system is installed at a university heating plant as part of an emissions compliance upgrade replacing boilers from the 1950's. The boiler surpassed all performance and emission goals.
