SU17575A1 - Modification of the firebox - Google Patents

Description

Grant No. 11759 describes a firebox, 0, leaving two zhamyrs with ring-shaped trays, rotating around Stokov, equipped with channels for supplying BOSAyxia; The frit is fed into the furnace using a screw, at which fero in the first chamber is burned only with one turn of the pallet, after which the waste is drawn into the second chamber, designed to burn up these wastes and transfer the unburned residues to the ash chamber. ,

 In the proposed modification, instead of vzashchayuschysy pallets; rotates are applied; grid arrays with concentric arcuate grates are provided with scraper bars at the bottom for pulling the solis of the cone-shaped ash pan to the hopper.

In the drawing, FIG. 1 depicts a vertical, racial section of the furnace; FIG. 2 - top view of the firebox; fig 3 is a section through FIG. 2. Grate 1 with concentric arches} The grate bars are fixed on the fi-box 8, put on the fixed one-hundred-eight. with a slab supporting column 1 of refractory bricks, sleep- |

I bzhennuyu nozzles 3 for the supply of air I; the grille is supported by rollers 8, is provided with scrappers from below for scrapping ash from a cone-shaped ashpit 6 and is driven to rotate 9 with a worm gear and gear 12. The brick walls 10, 14 of i of the refractory brick are provided with a number of nozzles 16 for supplying air entering . channels 7.

The fuel is loaded with a screw 15 or through hopper hoses onto a slow, rotary grate 1, where it starts to burn; as the fuel burns, its layer becomes thinner, but due to the spiral wall of the lining, the thickness of the layer increases, causing its activity to increase and the excess air decreases; after one lattice turn, the remaining unburned fuel and slags, removed by a slag picker 4, are tilted along the inclined wall 5 onto the lattice 11 to afterburn the same device as before. grid 1, from where the residue is dumped into the ash bin 18. i
