Definitions
- a device for re-firing the combustion products of the furnace is a device for re-firing the combustion products of the furnace.
- the present invention relates to furnaces, in particular to auxiliary devices for re-firing combustion products. And it is designed to work with a homogeneous solid type of fuel.
- the object of the present invention is to install equipment for re-calcination of combustion products in existing furnaces or to improve new models of furnaces / boilers. With the help of this equipment such problems have been solved.
- existing heating boilers such as slow ignition, smoke out and fire extinguishing, as well as ignition became faster, the gas conversion process, smokeless process and combustion process are improved, and energy saving, environmental protection and the service life of the combustion plant and stove are ensured.
- problems of existing heating boilers such as slow ignition, smoke output and fire extinguishing, have been solved, and ignition has become faster, the gas conversion process, smokeless process and combustion process are improved, and energy saving, environmental protection and prolongation are ensured. the service life of the combustion plant and the furnace.
- the technical result is to accelerate the ignition of fuel and improve the combustion of fuel in the furnace.
- the device for re-firing combustion products is made in the form of a hollow body with an inlet lower and an outlet upper holes, on the side wall of which there is a horizontal row of evenly spaced air holes.
- a flat rectangular protrusion is made on the inner side of each hole.
- the body can be made in the form of a truncated cone or a truncated pyramid or a truncated parallelepiped or a cylinder, or other body suitable for the hearth on which it is installed.
- the thickness of the rectangular protrusions is preferably less than the thickness of the body.
- FIG. 1 is an example of using the proposed device for re-firing combustion products in a furnace
- FIG. 2 - a variant of the proposed device and the hearth on which it is installed;
- FIG. 3 - drawing of the proposed device (cone-shaped);
- FIG. 4 is a drawing of the proposed device (pyramidal).
- reference numerals designate the following reference numerals.
- the equipment for re-burning the combustion products is a device consisting of a combustion body 14 and air holes 5 (see FIG. 3), the size is based on the design of the combustion furnace.
- the auxiliary projection (shutter) of the device for re-burning the combustion products in the furnace 15 is located inside the combustion body 14 and is located vertically on the wall of the combustion body 14 on both sides of each of the holes. but not necessarily strictly vertical.
- the size of the protrusion (1 - 2 cm), as a rule, does not exceed the diameter of the hole.
- auxiliary combustion projections (shutters)
- the thickness of the auxiliary projections is smaller compared to the thickness of the body of the device itself.
- the device for re-firing combustion products 12 is located above the ceramic hearth (furnace combustion unit) 1 inside the furnace body.
- the air holes 5 lie in the same horizontal plane and are evenly distributed along the side wall of the housing of the proposed device 15.
- the air chamber 7 is level with the air holes 5 and freely supplies air to the holes 5.
- the thickness of the auxiliary ignition projections (shutters) is comparative thin, therefore, when burning fuel, the temperature of this chamber instantly rises to the required ignition temperature, and the combustion process is not only fast, but also smokeless, and the fuel is completely burned, which meets environmental requirements.
- the body of the proposed device 14 has auxiliary protrusions (auxiliary combustion device), due to which additional air is supplied to the combustion body 14 from the outer openings of the furnace 4 (Fig. 1), which provides accelerated combustion of the residual combustion products (smoke).
- the body of equipment for re-firing combustion products can be conical or spherical column or square, square conical, rectangular, rectangular and other shapes, depending on the shape of the oven.
- the presented equipment for re-firing of combustion products is made of cast iron or iron industrially (on special equipment for metalworking), the quality and service life depends on the quality of the metal.
