1,081,002. Hot water boilers. F. KAY and J. L. BALL. Jan. 6, 1966 [Jan. 8, 1965], No. 861/65. Heading F4W. In a solid fuel or oil-fired water heater, smoke, in the combustion products from a combustion chamber 4, is consumed at the flue throat 8 by a flame curtain, produced by a burner tube 2 having a plurality of gas burner jets 3, and then takes a circuitous path defined by baffles 10 around the water tubes 12 before entering outlet 11. In a modification (Fig. 3), the burner tube 2 is again located within a flue throat (21) but the latter is positioned so that said burner can play on solid fuel supplied by hopper (17) to the inclined grate (15). The gas burner may be used in addition for lighting the solid fuel fire. In both embodiments, as a result of convection, heating of the water tubes may be achieved by the use of the gas burners alone.

For utilizing high volatile solid fuel in a domestic central heating boiler, a combustion chamber 1 of inverted frusto-conical form having a fire bed 2, which may be detachable, at its apex is completely enclosed by a water jacket 3, serially connected with a heat exchanger 4 surrounding a gas exit flue 5. Due to the shape of said combustion chamber 1, solid particles entrained in the waste gases fall back, facilitating smokeless operation at any temperature. Fuel is fed from a hopper 6 by a roller feed 7 to the bed 2 through the centre of a vertical air feed annulus 8 terminating in a ring 9 containing a plurality of air outlets. The fuel is ignited by a hot-air igniter 10 automatically controlled by a switch (not shown) connected to means responsive to the water temperature in the jacket 3, thus providing intermittent operation of the boiler ...

Pellets of soot and gas oil from a hopper 9 are fed by a vibrating shoot 10 to tube 17 in which a flexible wall rests on the fuel in the shoot. Compressed air fed into the tube 17 at 11 equalises the pressure in the tube 17 and that in the gasefication chamber 1 where the pellets are disintegrated, the oil being gasefied and partly burnt in a fluidized bed of pellets maintained on the grid 8 by the primary air supply 5. The soot particles and hot gases. pass into the cylindrical. combustion chamber 2 which has a tangential secondary air supply 6. A lip 13 projecting into the restricted passage between the gasefication chamber 1 and the combustion chamber 2 prevents the secondary air from reaching the gasefication chamber.
