Description

one

The invention is fireproofed and designed for radiant ceiling space heating.

According to the main author. St. No. 289263 is a one-time heating device known, comprising a housing composed of sections mounted on a perforated pipe for collecting Combustion Products, a burner and a pipe for discharging combustion products.

A disadvantage of the known device is the overheating of the upper wall of the housing sections and, as a result, the efficiency of the device to decrease.

The purpose of the invention is to reduce the overheating of the case and increase the efficiency of heat transfer. . .

This goal is achieved by the fact that a partition is installed in the cavity of each section, which forms a gas-tight compartment with the upper and side walls of the sections in which guides are placed, forming a labyrinth channel for the passage of heated air.

FIG. 1 shows a gas heater; fig 2 is the same top view; in fig. 3 - the same, axonometrics.

The gas heater includes a housing 1 composed of sections 2 mounted on a perforated pipe 3 for collecting the combustion products, a burner 4, a pipe 5 for discharging the combustion products. In sections 2, a partition 6 is installed, forming a gas-tight compartment 7, in which neperopotb guides 8 are placed, forming a labyrinth channel 9 with outlets 10, connected via pipe 11 to the air circulation system.

The operation of the instrument is as follows.

Case 1 is installed at an appropriate angle by rotating its sections 2 around the perforated pipe 3, the products of combustion pass through the cavities of the sections of the case, heat them through the holes of the perforated pipe 3, and then through pipe 5 to remove its products
