INVENTION
Russian Federation Patent RU2147106
SOLID HEAT
Name of the inventor: Yakovlev YV .; AE Rumin
The name of the patentee: Yakovlev Yury; Ryumin Alexander E.; Vladimir Gorelov
Address for correspondence: 601900, Vladimir region, Kovrov, ul.Shmidta, 9, kv.269, Ryumin AE.
Starting date of the patent: 1997.12.03
The heat source for use in heating engineering. The heat generator includes a housing, a furnace grate, having air ducts, gas-air heat exchanger, coolant fan and chimney. The grate may be formed in a lattice shape consisting of elements of tubular shape with longitudinal channels for coolant flow (air). In the absence of the air blast furnace separate device necessary for combustion of fuel passes through the fuel layer in the openings formed in the grate. To control the fuel combustion process in the longitudinal channel is fitted with a valve. The design of the heat source can increase the service life of the grate while reducing the size and weight of the heat generators.
DESCRIPTION OF THE INVENTION
The invention relates to the field of heat.
Known solid fuel heat source (Aut. 12460 certificate 1929, 2 pp.), Including a furnace grate-gas heat exchanger, coolant fan, hood, chimney.
Grate in that the heat source has a limited lifespan, so it is in the location of the furnace thermal stress. In this case the heat from it is not given, so it should be carried out from a massive heat-resistant materials.
The existing heat generators used for heating of buildings and structures, and also for drying of various materials (wood, grain, etc.).
The invention is aimed at increasing the service life of the grate by reducing the size and weight of the heat generator, but also to replace them by cheaper heat-resistant materials with less expensive.
The essence of the invention is that a heat generator comprising a housing with a grate furnace, gas-air heat exchanger, the coolant fan and chimney grate through the channels formed in it, part of the coolant is blown (air) stream by heating it. Other (main) part of the coolant flow through the heat exchanger and is warmed therein. This grate additionally performs the function of the heat exchanger by reducing its dimensions.
The invention is illustrated in FIG. 1 and 2, where FIG. 1 is a perspective view of a heat source, and FIG. 2 shows a grate grate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS to obtain the above technical result are as follows.
Heat generator (FIG. 1) includes a casing 1, with the furnace grate 2 3 having air channels 4, 5-gas heat exchanger, the coolant fan 6 and the chimney.
HEAT WORKS AS FOLLOWS
The coolant (air) pressure created by the fan coolant 6, falls under the hood 1 and rushes into the gas-air heat exchanger 5. A portion of this air enters the air channels 4 grate 3 mounted in a stream 2, where the air is heated by the air channel walls 4, the cooling grate 3.
The grate may be formed in a lattice shape (FIG. 2) consisting of tubular elements 1 to form three longitudinal channels for passage of coolant (air). In the absence of the air blast furnace separate device necessary for combustion of fuel flows into the fuel layer 2 through the openings formed in the grate. In this case, to regulate the fuel combustion process to the longitudinal channel 3 mounted adjustable throttle 4.
The invention is used as a solid fuel combustion systems in air-cooled heat source. In a standard axial or centrifugal fan as the coolant fan. This technical solution is tested on heat generators VZGA series. Test results have shown the effectiveness of the proposed solutions.
CLAIM
1. The heat generator comprising a housing with a grate furnace, gas-air heat exchanger, the coolant fan and chimney, characterized in that the grate has at least one channel for coolant flow passage portion.
2. The heat generator according to claim 1, characterized in that the grate is in the form of individual tubular elements.
3. The heat generator according to claim 1, characterized in that the grate path for coolant flow through holes connected to the furnace.
4. The heat generator according to claims 1 and 3, characterized in that the grate path for coolant flow, has an adjustable throttle.
