Abstract
1344228 Air heaters; air conditioning WERKTUIGENFABRIEK MULDER NV 19 May 1972 [24 May 1971] 23735/72 Headings F4S and F4V In an air heater for use in a central heating system, recirculated air to be heated supplied by a fan 27 is passed through a heat exchanger compartment comprising a plurality of rows of finned vertical tubes 2 through which flow combustion gases from a burner unit 5 located therebelow, the heated air being discharged from the heater through a duct 26. The burner unit comprises a separate burner 4 for each row of finned tubes 2, and the top of each burner has a series of perforated outlets 3 each of which is coaxially aligned with one of the tubes. Each outlet comprises a perforated disc-shaped region made up of a series of parallel corrugated strips separated by straight spacer strips. Combustion air is supplied through a duct 10 and the combustion gases, on passing upwardly through the tubes, leave the heater by way of a flue compartment 6 and discharge duct 12. To improve heat transfer between the combustion gases and air, the finned tubes are provided with baffle members for example in the form of inverted double cones 32, 33 made of refractory material or metal, the outer cone 32 being perforated throughout its height. A filter cloth or gauze 28 mounted adjacent the fan inlet removes dust &c. from the recirculated air stream entering the heater. Water vapour may be added to the heated air stream in compartment 7 via a pipe 31, the water vapour being produced by heating water in a tank 29 mounted on top of the flue compartment 6. The amount of water vapour added is automatically controlled by a room hygrostat controlling an electro-valve for closing the water supply to the tank 29. Gas is supplied to each burner via a T-shaped tube 35 carrying nozzles 26, the tube 35 being connected to a control device 9 comprising an electro-magnetically operated gas shut off valve. Operation of each burner can be separately controlled by control means connected to a multistage room thermostat.
