Abstract

The invention can be used in devices for burning fuel in boiler units and can improve efficiency by improving the quality of burning fuel. A pair of burners 4 and nozzles 5, located in each pair in the same vertical plane, are installed on two opposite walls 2,3 of the vertical chamber 1 of combustion along with the slope downward. Burners 4 and nozzles 5 of all pairs are directed tangentially to a conditional surface common to all pairs of a horizontal cylinder 6. Burners 4 and nozzles 5 adjacent pairs can be installed along a wall width of 2.3 with mutual alternation. When the firebox is operating, the fuel-air mixture is fed through the burners 4 into the volume of the combustion chamber 1, and secondary air is fed through the nozzles 5. Due to the tangential orientation of the burners 4 and nozzles 5 to the common for all pairs of conditional surfaces of the horizontal cylinder 6, a vortex flare with high recirculating capacity is created in the volume of the combustion chamber 1, which improves the quality of fuel combustion and increases the efficiency of the furnace operation. 1 hp f-ly, 4 ill.

Description

FIG. one

The invention relates to a power system and can be used in devices for burning fuel in boiler units.

The aim of the invention is to improve efficiency by improving the quality of fuel combustion.

FIG. 1 shows a firebox, longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 - firebox, longitudinal section with a possible placement of burners and 10 nozzles; in fig. 4 shows a section BB in FIG. 3

The firebox contains a rectangular vertical combustion chamber 1, on two opposite walls 2 and 3 of which there are

The secondary air that is missing until complete combustion of the fuel is supplied from nozzles 5. Due to the tangential orientation of the axes of all pairs of burners 4 and nozzles 5 to the common for all pairs of conditional surfaces of the horizontal cylinder 6, the volume of the combustion chamber 1 creates a vortex flare with high recycling capacity, which improves the quality of combustion fuel and increases the efficiency of the furnace.

Claims (2)

1. A furnace containing a rectangular vertical combustion chamber on two with a downward slope installed a pair of burners. opposite walls of which are 4 and nozzles 5. In each pair of burner with a downward slope, there are pairs of burners 4 mounted on one of the walls, for example, air nozzles, and in each pair there are 2 combustion chambers 1, and the nozzle nagorelka is mounted on one wall and the opposite, for example, wall 3. The axes are on the opposite and their axes of the tan 4 and the nozzles 5 of each pair are gented to the conditional turn - in the same vertical plane. Burners 4 20 of the cylinder, characterized in that, c and the nozzles 5 of all pairs are directed tangentially to improve efficiency by improving to the conditional surface common for the quality of fuel combustion, the axis of all the pairs of the horizontal cylinder 6. arrows and nozzles each pair are located in one vertical plane, and the tangential direction of all the burners and nozzles is made relative to the conditional surface common to all pairs of the horizontal cylinder. 2. A furnace according to claim 1, characterized in that the burners and nozzles of adjacent pairs are installed; 1 the air-fuel mixture from the knee-Qena is fed across the wall width with a mutual alternating excess air ratio of 0.5-0.6. by the / 1- / 1 The burners 4 and nozzles 5 of adjacent pairs can be installed across the widths of walls 2 and 3 in alternation (as shown in Fig. 4). The furnace works as follows. From burners 4 to the volume of the combustion chamber The secondary air that is missing until complete combustion of the fuel is supplied from nozzles 5. Due to the tangential orientation of the axes of all pairs of burners 4 and nozzles 5 to the common for all pairs of conditional surfaces of the horizontal cylinder 6, the volume of the combustion chamber 1 creates a vortex flare with high recycling capacity, which improves the quality of combustion fuel and increases the efficiency of the furnace.
