FURNACE EQUIPMENT.
Application filed December 7, 1925, Serial No. 73,762, and in Canada December 17, 1924.
This invention relates to new and useful improvements in furnace equipment and is particularly adaptable to furnaces burning pea coal or screenings, and the object of the invention is to provide a forced draft equipment of simple construction which will assist in withdrawing the heavy discharge of explosion due to the rapid accumulation of gases 1n the furnace when using bituminous coal, pea coal or screenings.
' In burning bituminous, pea coal or screenings in furnaces, difliculty has been encountered in withdrawing the enormous amount of gaswhich accumulates within the furnace when blowing up a smouldering fire and accidents have occurred due to the explosion of said gases.
In my invention. I provide means for tapping some of the air supplied by an' under grate forced draught blower to increase the draught in the furnace above the fire, so that the products of combustion may be quickly withdrawn from the furnace.
draught equipment.
Referring more particularly to the drawing, 11 designates a furnace of the usual con- .therethrough. A smoke. or gas discharge pipe 19 is provided between the 'furnace smoke outlet-15 and the chimney (not shown). Between the blast pipe, 16 and the smoke pipe 19, air air duct or pipe 20 is provided, the lower end 21 of which is situated within the blast pipe 16"and bent towards theblower, as designated at 22. The upper end 24 of the pipe is positioned within the smoke pipe 19 and may be rovided with a nozzle 23. The discharge cm the "nozzle is in the direction of the arrow 25.
A Venturi tube 26 may fitted within the In the drawings, I have shown a partial sectional elevation of my improved forced pipe 19 in close proximity to the end of the nozzle 23, to increase the efiiciency of the draught through the pipe 19 in the well known manner. A damper or wing valve 27 may be placed in the pipe 19 to regulate the discharge of gases from the furnace.
In the drawing, I have shown the device in its simplest form, but it will be readily understood that modifications may be made in the construction without departing from the spirit of the invention.
In operation the device is very simple. To liven up a smouldering fire of closely packed pea coal or bituminous coal, the
blower is set in operation and a continuous blast of airv is driven through the pipe 16. Some of the air is driven into the furnace through the ash pit under the fire, which is packed on the top of the grate, while the rest of the air passes through the air duct or pipe20, through the nozzle 23 and direct to the chimney, not shown. This construct on creates a draught in the pipe 19 to withdraw the gases from. the furnace above the fire, thereby preventing accumulation ofsaid gases to such an extent thatan explos on might occur. It also assists in drawing the air delivered to the underside of the fire through the closely packed coal. thereby increasing the efliciency of the furnace. To further assist the efliciency of the demos. the
'Venturi tube is fitted in close proximity to the air duct.
Having thus described my invention. wnat I claim is The combination of a furnace having a grate and an outlet pipe for the products of combustion, an air blowerrhaving an a1r discharge pipe leading into the lower part of the furnace to supply air thereto at a point loo
