HTW heating system having an electrode steam boiler as the direct source of HTW

Patent ·
OSTI ID:6606221
A high temperature water (HTW) space heating system in which the direct source of HTW is an automatic electrode steam boiler having electrodes, adapted to be connected in an electrical distribution system is described. The electrodes are positioned in corresponding steam generating compartments surrounded by a control compartment. A corresponding water spout directs water toward the tip of each electrode. A regulating valve allows only a limited steam output, which is used for control purposes. Water is taken from the boiler and mixed with water from an outside source. A boiler water circulating group feeds the mixed water to the spouts with sufficient velocity for it to flow up the surface of the electrodes to the water level in the steam generating compartments. The system has a heated space circuit including a pump for circulating HTW. An HTW supply circuit connects the boiler with the heated spaces circuit and provides unrestricted flow of HTW from the boiler to the heated spaces circuit so that the boiler serves as a pressurized expansion tank for the heating system. A diversion circuit is connected between the heated spaces circuit nd the inlet of the boiler water circulating pump. A control valve arrangement diverts a controlled amount of HTW from the heated spaces circuit to the pump inlet through the diversion circuit. Such diverted HTW constitutes water from an outside source and is replaced in the heated spaces circuit by HTW from the boiler through HTW supply circuit.
