Abstract
Hot gases passing through the flue of a central heating or other furnace are used to heat air circulating through a heat exchanger surrounding the flue, for the purpose of space heating. <IMAGE>
Description
SPECIFICATION
Heating installation
In domestic heating installations, a substantial quantity of heat produced by a boiler, stove or other heat source is lost by discharge to the atmosphere through the flue. Various attempts have been made to conserve some of this heat, for example by incorporating a tubular coil in the flue, and passing air through the coil for space heating purposes, as disclosed in patent No. 1 161 483. This earlier arrangement has the disadvantage that the flue is obstructed and fitting is difficult.
The drawing is a diagrammatic illustration of an installation in accordance with the present proposal.
Referring to the drawing, hot waste gases from a heat source 1 are led to a flue duct 2 and discharged to the atmosphere. The heat source may be of any type, for example a gas or solid fuel central heating boiler, stove or furnance, or even an open fire, provided that the gases may be led to a conventional unobstructed stainless steel flue duct, or to any other duct suitable for use in carrying out the present proposal.
The duct is surrounded by a case 3 into which opens an air supply duct 4 and an air discharge duct 8. The air supply duct is fed by a fan unit 5 having a first inlet 6 incorporating a filter located externally of the building and a second inlet 7 located where it will draw in air at room temperature. The inlets are so dimensioned that about 75% of the air leaving the fan unit has been drawn from outside the building and about 25% from inside the building. The air discharge duct 8 has one or more outlets with the building.
Within the case 3 copper tubes 9 are strapped to the outer surface of the flue duct.
Air supplied to the casing flows through and around the copper tubes so as to take up heat from them. The tubes 9 are coated with black heat dispersant paint. The fan unit is controlled by a thermostat associated with the flue duct.
Depending upon the length of the flue duct or other factors, the flue duct may have an inlet 10 for the supply of a forced draught.
The fan unit 5 may be used to produce the forced draught or, alternatively, a separate fan may be used for this purpose and be electri cally interlocked with the fan unit 5.
The flue duct may also have a downward extension 1 2 with a drain tube to allow tar deposits to collect in a suitable receptacle 1 3.
The case 3 has a drain tube 14 to allow condensate to escape. Condensation is, nevertheless, inhibited to a large extent by arranging for a proportion of the air supplied to the heat exchanger to be at room temperature.
The present proposal may be employed in conjunction with domestic or industrial heating installations.
Advantages of the proposed installation are that a substantial amount of heat is saved which would otherwise be wasted, tar deposits are collected thereby reducing pollution, and condensation is reduced. A slight over pressure is produced within the building which leads to an increase in flue draught, and the provision of warm, fresh air leads to a more healthy environment.
1. A heating installation for a building comprising a heat souce, a tubular metallic flue through which hot waste gas from the heat source is discharged to atmosphere, a casing surrounding the flue, and air supply and discharge ducts opening into the casing to enable a stream of air to be passed through the casing, heated and vented to the building.
2. A heating installation as claimed in claim 1, wherein the supply duct is fed with air by a fan which draws air both from the atmosphere and from within the premises.
3. A heating installation as claimed in claim 1 or claim 2, including a branch connected to the flue for the supply thereto of a forced draught.
4. A heating installation as claimed in any preceding claim, wherein an array of copper tubes is secured to the flue within the casing.
5. A heating installation as claimed in any preceding claim, including drain tubes from the casing and flue respectively.
6. A heating installation in which a heat exchanger associated with a flue is supplied with air for space heating, the air being drawn from the exterior and the interior of the premises.
CLAIMS (8 May 1985)
