摘要:
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. 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 and 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.

A radiator for low-pressure steam heating systems comprises at least two chambers, which constitute respective radiator elements. Consecutive elements are interconnected in an upper portion and in a lower portion. The upper portion of each element is connected to a low-pressure steam source. The lower portion of each element is connected to a condensate trap. At least individual ones of the elements are adapted to be shut off from the steam supply.
摘要:
A space heater with a heat recovery system in which the exhaust gases from the hot air furnace are passed through a heat exchanger in which a set of water heating coils is disposed. The set of coils is connected to a hot water holding tank which is in turn connected to a bank of heat exchanger coils in the heated air outlet of the furnace. A damper is provided in the exhaust pipe of the furnace and a pipe connects the exhaust pipe on the anterior side of the damper with the heat exchanger, and a pipe connects the chamber with the exhaust pipe on the posterior side of the damper. A pump is provided for circulating the water between the first set of coils and the holding tank, and a fan forces the air form the exhaust pipe through the chamber in the heat exchanger. The pump and fan are controlled by a switch responsive to the operation of the furnace. The holding tank may be used to heat water supplied to a hot water heater of a hot water supply system.

A system is provided for obtaining steam directly from an HTW heating system for heating the upper levels of high buildings. The system comprises a source of high-temperature water, means for separating said water into a steam portion and a hot water portion, means for heating spaces of the upper levels of the said building with said steam portion and means for heating spaces of the lower levels with said hot water portion, means for controlling the temperature of said heated spaces and means for returning the said water to said system.
