    Hart's Improved Apparatus for Consuming Smoke in Furnaces. According to one mode of carrying out my Invention as applied for example to a double cylindrical flued boiler with external side flues, I place in each of the side flues a pipe or tube of metal, fire-clay, or other suitable material, the ends of these pipes farthest from the front of the boiler being open to the atmosphere. Across the front of each 5 furnace there is fitted another pipe or main into each of which the front ends of the first-mentioned pipes open. Prom these transverse pipes or mains branch off a number of smaller pipes, say four to each furnace, such pipes passing longitudinally close uuder the grate bars and opening at their rear ends into a transverse perforated or slotted 10 pipe let into a channel in the fire bridge, or the pipes may discharge themselves into a hollow fire-clay bridge instead of the slotted pipe. The cold air which first enters the pipes has its temperature gradually elevated as it passes along to the front mains, and on passing through the branch pipes immediately beneath the fire bars it becomes highly 15 heated, in which condition it issues in a divided state or in the form of a thin sheet from the perforated pipes in the fire bridge, and by mingling with the smoke and unconsumed gases effects their immediate consumption.
