Description

Firing for tubular boilers with a fire screen built into the fire box and air supply chamber sitting on it. Firing for Rährenkessel with in the Fire box built-in fire screen and air supply chamber sitting on it.

The invention relates to a device for perfecting combustion with stationary and moving tubular boilers with a fire screen built into the fire socket and a second fire screen sitting on it with air supply chamber, which with Flue pipes of the boiler loosely connected and through the smoke chamber by means of pipe sockets and lead the bottom of the smoke chamber into a suction nozzle.

Through this facility, additional heated air is passed through the front End of the incandescent fire screen, causing the in the fire socket any smoke gases and soot formations, - those in contact with the fire screen come, ignite and burn.

Fig. I shows a tubular boiler in a longitudinal section with the device. Fig. 2 shows the fire screen with fire screen attachment in cross section, Fig. 3 in longitudinal section, Fig.q. in plan and the extension of the smoke tubes in the fire screen attachment. Fig. 5 and 6 show the extension of the smoke tubes in the smoke chamber in cross section and longitudinal section.

The arrangement of the fire screen 2 has the advantage that if during the drives due to strong bumps or the like de, the fire screen attachment comes out of its position, it immediately goes back to its old position. It further aims that at the reloading of the fire, where "the soot formation and smoke gases are sharpest distinguish, the combustion process starts immediately by placing a first. Jet flame arises that. immediately spreads further and consumes all combustible particles.

This effect is achieved because: ß the fire screen 2, which is kept smaller than the fire screen r, blows additional air through its air supply chamber 5 over the incandescent fire screen r. The flue gases and carbon black fluff, the screen come into contact with the fire, are mixed with the additional air and ignite ' at the whitewashed an Feuerschiam r. Here- by creating a new jet of flame, by. Abundance of oxygen builds up which transfers other combustible particles and also: this completely for incineration brine-t. Additional air never enters through a suction pipe 4 attached below the floor of the smoke chamber, its. Muzzle adjustable is. From, this suction tube which bundled together air-supply pipes 3 pass through the bottom of the smoke chamber, chamber and opening into the lower flue tubes of the boiler, which in the fire-box through the fire screen 2 welscher provided with the air supply chamber 5, is, covered by the smoke 'itself are.
