For this purpose, too, it is desirable to have a blow-off cock attached to any convenient part of the annular space g,g. m, m, is an air-tight chamber which may be formed on the bottom of the ash- pan as shewn, or may be placed in any other convenient position. This chamber is supplied with atmospheric air, steam, or other gas or vapor by the 5 air pumps p, p, at any desired pressure, worked from the eccentrics or otherwise. The communication between the pumps p, p, and the chamber m9 m, is furnished with a two-way cock, or other means of changing the supply to the chamber from the pumps p, p, to the atmosphere direct. Where a 46 donkey engine ” is used, its ordinary water pump can be con- 10 verted for the time being, into an air pump by having two-way cocks or other suitable valves for shutting off the communication between the water and the boiler, and supplying the pump with air and enabling it to commu¬ nicate with the chamber m, m, so that when the engine is not working, the “ donkey ” can by this means keep up the supply of air, steam, or other gas 15 or vapor required for the combustion of the smoke and other gases of the fuel, as before described. By the foregoing description it will be seen that by the pump p, p9 the chamber m, m, and the pipe or passage h, h, can be supplied with air, steam, or other suitable gas or vapour at any pressure, and that in passing along that 20 portion of the passage h9 h, which is lined as before described, the air, steam or other gas or vapor must become heated, and that when it arrives where the spaces have been left between the tubes /, /, it will rush through these slits in every direction with a force proportioned to the pressure used, and thoroughly intermix with the smoke or gases of the fuel, and by the oxygen 25 which it conveys causing more perfect combustion ; the number of these compound pipes h, h9 may vary, there may be one, two, three, or more, as the size and requirements of the furnace or fire-box may determine. The ash- pan d, d, and chamber m, m, must be attached to the fire-box in such a way as to allow sufficient motion to meet the expansion and contraction of the 30 tubes /, /. It is not necessary that the air, steam, or other gas or vapor be forced into the chamber m9 m9 by air pump p, p, as this may be effected by fans or any other ordinary mode of moving elastic fluids. The joint of the flange g, g, with the tube e9 e9 being made with bolts and nuts, and the connections of the pipes iy i, k, k9 being properly arranged, the compound pipe 35 or tube may be removed with facility when required. The compound heating and distributing tubes may be constructed in several other ways than that described, one of which I have shown in the Drawings 3, 4, 5, 6, and 7, and it is not essential that the air, steam, or other
