Description

Patent No. 2763 describes a collapsible oil on a firebox in which a nozzle is applied, which serves to supply air to the pan and washes the outside with combustion products, passing first through the channel located under the pan and then over the slab placed over the pan. In the proposed modified furnace, the stove placed above the frying pan has a fracture, and the fins of the frying pan are brought to the stove, forming a zigzag channel, in order to lengthen the path of fuel and air for better utilization of the fuel.

In the attached drawing of FIG. 1 shows a longitudinal section of the furnace; FIG. 2- its cross section; FIG. 3-top view of the pan; FIG. 4-view it from the side.

The furnace consists of a bottom / (Figs. 1 and 2) on which walls 2 and a door 9 are installed, which are topped with a plate with several longitudinal openings for the exit of combustion products, provided on both sides with one longitudinal and one

transverse, vertical ribs; A second plate 4 is laid on top of the plate 3 with the same openings with downward-facing ribs on two other sides, so that the openings are surrounded by ribs on all sides; due to this, heated air passages are formed between the plates. Inside the furnace, near its longitudinal walls, there are two air-heating boxes 5 and 6 with openings on the walls facing inward; Above these boxes, jio is placed a frying pan / 7c with a tray M, covered with a plate K (FIG. 5) composed of two parts connected at an angle between themselves. Frying pan H is provided with angles 7-70 located at an angle to its longitudinal axis. 3) reaching the lower surface of the slab and forming a zigzag channel; the bottom of the pan in the back has a bend / 7. The assembled firebox is inserted into a crank oven or into a kitchen hearth; if the furnace is to be used as an independent stove, then a lid is installed on it. a hole for the outlet pipe. A wire ring / 2 is inserted in tray M to secure the tube from the liquid fuel tank therein. The products of combustion occurring in the pan H, heating the stove K, are lowered under the pan and go through channel A to the front wall of the tsagrev oven / the pan; then, covering on both sides the chute M, is lifted into the space B, from where it passes through the hole in the upper plates to the chimney. The ribs placed in the pan H lengthen the path of fuel and air, which contributes to

its heating, complete combustion of fuel and increase in gi. The 1J bend aims to facilitate the heating and speedy heating of the bottom of the pan, where the liquid fuel is turned into gaseous state and mixes well with the air of the furnace.

The subject matter of the invention.

Modification of the firebox according to patent No. 2763, characterized in that the plate K, placed above the pan H, has a fracture, while the ribs 7-10 of the pan are brought to the plate L, forming a zigzag channel.
