Abstract
Abstract 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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
83 words
An HTW heating system for a high-rise building having several levels comprising means for producing 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 back pressure controlled means for returning the said water to said system.
Claim 2
Dependent Claim
83 words
An HTW heating system for a high-rise building having several levels comprising means for producing 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 back pressure controlled means for returning the said water to said system.
Claim 3
Dependent Claim
23 words
An HTW heating system according to claim 1, wherein the proportions of steam and hot water are determined by the controlled steam pressure.
Claim 4
Dependent Claim
18 words
HTW system according to claim 1, including means for adjusting the proportion of heat supplied to separate spaces.
Claim 5
Dependent Claim
103 words
A process for heating a high-rise building which comprises discharging high-temperature water from an HTW heating system into a vessel maintained at a relatively low pressure, thus dividing the high-temperature water into flash steam and hot water at saturation temperature, heating the upper levels with the flash steam and heating the lower levels of a high building with the hot water, discharging the condensate from the steam-heated radiators and the water from the hot water radiators through back pressure control valves into a vessel maintained at atmospheric pressure, and pumping the mixture of condensate and hot water back into the HTW heating system.
Claim 6
Dependent Claim
103 words
A process for heating a high-rise building which comprises discharging high-temperature water from an HTW heating system into a vessel maintained at a relatively low pressure, thus dividing the high-temperature water into flash steam and hot water at saturation temperature, heating the upper levels with the flash steam and heating the lower levels of a high building with the hot water, discharging the condensate from the steam-heated radiators and the water from the hot water radiators through back pressure control valves into a vessel maintained at atmospheric pressure, and pumping the mixture of condensate and hot water back into the HTW heating system.
Claim 7
Dependent Claim
41 words
A process according to claim 4 whereby a surplus of hot water is provided, the said surplus of hot water being discharged directly into the said vessel receiving the condensate from the steam-heated radiators and the water from the hot-water-heated radiators.
Claim 8
Dependent Claim
23 words
An HTW system according to claim 1, including means for returning a controlled amount of said hot water portion directly into said system.
Claim 9
Dependent Claim
59 words
An HTW heating system according to claim 1, including automatic control devices for regulating (a) the steam pressure and water level in the vessel into which the high-temperature water from the HTW heating system is discharged (b) the temperature of the heated spaces and (c) the water level in the vessel receiving the condensate from the steam heated radiators.
