Steam heating system and condenser therefor

摘要

A system for supplying steam to equipment which uses the heat of the steam and not the pressure for performing work such as commercial laundry equipment. The system is a closed loop having a steam boiler which supplies steam directly to the equipment. A control valve regulates the amount of steam flowing through the equipment which determines the heat imparted to the equipment. The equipment is free of heat traps or other components which retard the flow of steam therethrough. The used steam flows into an improved condenser having a plurality of compartments which slows down the velocity of the steam to help facilitate the condensing process and to enable harmful air trapped in the condenser to be removed. Pumps remove the air from the condenser and maintain a vacuum within the condenser and steam return line from the equipment to maintain the steam flowing through the equipment at a desired rate. Cooling water circulates through individual coil groups within each condenser compartment for condensing the returning steam. The cooling water is heated by the steam and transferred to a hot water storage tank for use in other operations of the laundry.
