'~mcKs Improvements in the C^rmtion of Smoke-consuming Furnaces. blast pipe and in place of the ordinary fire-bars which would be melted by so great a heat, I place a grid formed of fire-clay or fire-brick^ as a distributor for the blast before it enters the furnace bed. At any convenient point in the blast pipe I attach a branch pipe, and by employing valves above and belowr the junction of the pipes, I can shut off the blast, and take the smoke from 5 the chimney when the damper is down, causing the smoke to repass through the fire; this is for the purpose of allowing the stoker to clean out the furnace.
