Indeck Keystone Energy, LLC Delivers Massive Shop-Assembled Watertube Boiler

Industrial Boiler Systems - Indeck Power Equipment Company

Indeck Keystone Energy’s technology center has completed the custom engineering and manufacture of one of the largest shop-assembled boilers in the United States. Indeck Keystone Energy delivered this massive Keystone watertube “D” type package boiler for a major steel manufacturer in the Midwest. The boiler weighed nearly 1,000,000 pounds and required tremendous efforts to move it by land and sea to the client.

Design of the large boiler involved engineering, manufacturing, and transportation considerations. The custom designed Indeck watertube boiler included 100% tube and membrane furnace and sidewalls to increase boiler life while reducing overall maintenance. Engineering of the boiler took into consideration combustion, emissions and optimization of boiler heating surface and tube spacing for enhanced thermal performance. The boiler design also included provisions to be lifted via a heavy haul multi-axle truck equipped to travel over the road and onto a barge for water transport.

According to Chris Petcos, Chief Operating Officer, “Indeck Keystone Energy was selected because of our past history with large custom designed specialty boilers, project management expertise, schedule compliance, competitive price and ability to offer shop assembly of the boiler module. With extensive experience in designing boilers firing low BTU fuels such as blast furnace gas (BFG), coke oven gas (COG) and landfill gas, the Indeck team enjoys working with the most demanding of clients to supply industrial boilers for processing, manufacturing, and petrochemical refining applications worldwide.”
