Heat recovery system removing heat from waste water - by using it to heat up fresh water, domestic or industrial

The temp. of the used water and that of the water for use are continuously measured. When the temp. of the used water is higher than that of the water to be used, the used water is directed through a heat exchanger where it preheats the fresh water. The waste water is rejected directly when its temp. is lower than that of the fresh water. By removing heat from the waste water before it is discharged, thermal pollution is avoided and energy saving is achieved.

Heat economiser for liq. or gas fired central heating boiler - has thermostatically controlled motor driven shutters which selectively channel smoke through tubes connected to water circulation system

The arrangement uses a tripple-action, automatically operated, motorised shutter. An enclosure interconnects the boiler with the chimney and contains a system of tubes connected to the boilers water circulation circuit. The shutter is situated on the smoke outlet and can either shut the smoke outlet, or bypass the tubes. In a third position, the shutter forces the smoke to pass through the tubes. When the temp. of the smoke is sufficiently high, as determined by a thermostat at the output of the enclosure, the shutter adopts the position which forces the smoke to pass through the tubes which form a heat recuperator. When the boiler is turned off, the shutter causes the smoke outlet to be shut. The action of the shutter is progressive and the arrangement is completely isolated to reduce heat losses.

Recovery of heat from mixt. of waste steam and air - which is drawn by suction fan through condenser to obtain hot water usable in mfg. processes or for heating

A mixt. of atmos. pressure, contg. steam and air, is released by an industrial appts. into the environment. The outlet chimney of the appts. is provided with shutter valves and a by-pass duct leading to a condenser fitted with a suction fan, so part or all of the mixt. can be drawn through the condenser. The amt. of the mixt. fed through the condenser is controlled by adjusting the valves to control the pressure in the chimney or the temp. of the mixt. In the pref. plant, the suction fan is located in an air outlet duct near the exit end of the condenser; and another shutter valve is used to control the vol. of air drawn through the by-pass and the condenser. Used for esp. on baking or cooking plants which produce substantial amts. of steam released by the materials or prods. being cooked, where the steam is condensed to obtain hot water used in mfg. processes or to heat buildings. Virtually all the heat in the steam can be recovered without interfering with the cooking or baking plant, which normally uses natural draft.
