Description

0U9.f

The invention relates to a power system and can be used in burner devices of boilers and heat units operating under various vacuum conditions and pressures.

The purpose of the invention is to increase profitability by improving the mixture formation

Figure 1 shows the intended burner, longitudinal section; Fig. 2 shows section A-A in Fig. 1; Fig. 3 shows the profile of a fan blade with an impeller blade; figure 4 - the same, axonometrics.

The burner contains an air supply housing I with an axial fan 2 with blades 3 carrying blades 4 turbines, opposite to which gas-feeding nozzles 5 are mounted on the housing 1. in the middle of the blades 3 and parallel to their edges 6 and 7.

The peripheral ends of the 8 blades 4 of the impeller are fastened to the front edges of the 6 blades 3 of the fan 2 with the help of additional arcuate partitions 9, and the gas supply nozzles 5 are tangentially relative to the conventionally drawn circle passing through the middle of the front surfaces of the blades 3 of the fan 2.

The burner works as follows.

The air sucked into the housing 1 by means of the fan 2 approaches the blades 3 and, the passage between them, is mixed with the exhaust gas on the blades 4 of the gas turbine supplied from the nozzles 5. The resulting gas mixture moves to the output section of the burner and burned at the exit of it.

The blades 3 of the fan 2 rotate due to the kinetic energy of the jet

the gas supplied from the nozzles 5 and striking the working surface of the blades 4 of the gas impeller. Moreover, the gas jets first flow around the front edges of the edges 6 of the blades 4, then its working part, where they change their direction almost in the opposite direction, and, streamlined, the output edges 7 and give their kinetic energy to their maximum, leaving the downstream edges of the 7 blades 4 are connected to the middle part of the width of the blades 3, the upper part of the latter becomes, as it were, a continuation of the output edges of the 7 blades 4, i.e. The output edges 7 of the gas impeller blades 4 are longer than its front edges, which allows a deeper use of the kinetic energy of the gas jet to convert the mechanical rotation of the fan 2 into mechanical energy and improves the mixing of the aza with air, which increases the efficiency of the burner.
