Project Description:

ESI was the engineer for this 37 MW wood-fired power generation facility. The facility includes a field-erected wood-fired boiler designed to provide 1200 psig/950°F superheated steam to a nominal 37 MW steam turbine generator. A portion of the 325,000 pph of steam is utilized to provide hot water to the St. Paul Central Heating Plant. This facility also includes a complete material storage and handling system, ash storage and handling system, reverse osmosis water treatment system, deaerator, boiler feedwater pumps, SNCR system, precipitator, continuous emission monitoring system, Westinghouse distributed control system, and a new 50,000-gallon capacity #2 fuel oil tank. This system was housed in a new engineered structural steel building.
