Records at the plant indicate that heating costs with the old boiler system ranged between $700,000 and $1,000,000 a year, not including the cost of steam used in the production process. "With the Space-Ray heaters, energy costs have been ranging between $135,000 to $200,000 a year, depending on the severity of the winter," Allgyer said.
Read MoreLow pressure steam or hot water boiler means an electric, gas or oil burning furnace designed to supply low pressure steam or hot water for space heating application. A low pressure steam boiler operates at or below 15 pounds psig steam pressure; a hot water boiler operates at or below 160 psig water pressure and 250 °F. water temperature.
Read MoreBoiler Efficiency. The ratio of the useful heat output to the heat input multiplied by 100 and expressed as a percent. Boiler Rating. The rating of a steam boiler expressed as the total heat transferred by the heating surfaces in Btu per hour. Sometimes also expressed in horsepower or pounds of steam per hour. cycle oil from a fluid
