TEPLOGENERATOR "RYAZAN-2"

The "Ryazan-2" heat generator (see drawing) contains a coolant cooler 1 with a pressure head 2 and a suction port 3, a coolant circulation pipe 4, a jet device 5 with a nozzle 6, a gas supply pipe 7 and a mixing chamber 8, a gas-liquid mixture separator 9 with a branch pipe Removal of the heat transfer medium 10 and the gas chamber 11 with the gas removal pipe 12, the oxidant heater 13 with the supply branch pipe 14 and the oxidizer discharge pipe 15, the two heaters of the heated product 16 with the branch pipes 17 and the product outlet 18, and the coolant outlet 19. In addition , It comprises a grate furnace 20 with a grate 21, a solid fuel supply door 22, an ash hopper 23 and an oxidant supply connection 24, a flue 25 with a gas outlet 26, a product superheater 27 with a product supply pipe 28 and a hot product outlet 29, A superheater 30 with a steam inlet 31 and a branch pipe for the superheated product 32. A and comprises a burner 33 with a fuel supply connection 34 and a hot gas supply connection 35. Contains a product heat exchanger 36 with an inlet branch 37 and a product outlet 38. Contains a steam generator 39 comprising A steam chamber 40 with a steam discharge port 41, a spray nozzle 42 with a superheated product inlet branch 43, a chimney outlet for the cooled product 44. Contains a product blower 45 with a suction 46 and a discharge nozzle 47.

The movement of the streams is indicated by arrows. From the supercharger 1 through the pressure connection 2 of the coolant, the liquid under pressure is directed to the jet apparatus 5. Passing the nozzle 6, the liquid acquires a high speed in the form of a compact jet due to lowering the pressure (lower than in the furnace). The combustion device 20, for example, a burner 33, operates with fuel supply through the branch pipe 34 and the oxidant through the heating pipe 14 in the preheater 13. The combustion product (gas) sucked by the jet device passes through the gas duct 25, transfers some of the heat to the superheater 30 and the product superheater 27 , Through the pipe 7 comes into contact with the jet of liquid. At the initial section of mixing chamber 8, intensive evaporation of liquid from the surface of a single jet, washed by hot gas, takes place. The gas is cooled by mixing with the superheated steam of the coolant, and also giving part of the heat in the heat exchanger 36. The temperature of the jet core does not change. Then the stream begins to disintegrate, which is facilitated by evaporation from its surface and release of bubbles of dissolved gas. Liquid droplets fill all sections of the mixing chamber, involving a vapor-gas mixture in the flow. The jet nucleus disappears, and the entire space is filled with a homogeneous gas-liquid flow. The velocity field over the section is equalized, the pressure increases. In the flow there is a contact heat exchange between the gas and the liquid, condensation of the vapor and the precipitation of solid particles (ash, soot). The liquid is heated by cooling the gas and condensing the vapor. There comes a temperature equilibrium. In the separator 9, the gas-liquid mixture is separated. The separated gas, saturated with steam, passing through the heaters 16 and 13, irrigated with cold liquid coming from the injector 51, is cooled, the excess vapor condenses. The gas is removed through the nozzle 12, for example into the atmosphere, and the condensate flows into the separator by gravity. The heat carrier saturated with dissolved gases (CO 2 , N 2 , air, etc.) passes through a preheater 16 located in the pipeline, cooled, then through a filter 48 where solids are deposited, and the branch pipe 3 returns to the heater 1.

The heated product (liquid or gas) passes through three heating stages in the preheaters 16 with the product supply pipes 17 that can be connected in series or in parallel, as shown in the drawings, in the heat exchanger 36 and in the product overheater 27. The superheated product (liquid) then enters The steam generator 39 through the nozzle 43 and the spray nozzle 42, at the outlet of which the pressure drops below the saturated vapor pressure of the product at its temperature. Sprayed product boils, partially evaporates, its temperature drops. The cooled product through the pipe 44 by the blower 45 is directed to the product superheater 27. The saturated steam through the branch pipe 41 is directed to the superheater 30. The superheated steam is delivered to the consumer through the branch pipe 48. The superheated product is delivered through the pipe 29. The coolant is supplied through the branch pipe 52 and Sprinkler-irrigator 51.

In the furnace you can burn any kind of fuel at atmospheric pressure. Coal, peat, and firewood loaded onto the grate 21 through the door 22, with ash removed through the ash hopper 23 and by the oxidant through the heating pipe 14 in the preheater 13. The gaseous or liquid fuel at elevated pressure or pulverized through the pipe 34 is burned In the burner 33. It is also possible to use secondary, waste heat, removed from the heaters (boiler rooms, smelting ovens, dryers), through the branch pipe 35.

Direct contact of the coolant with flue gases in the jet apparatus 5 followed by sub-cooling of the gas in surface heaters 16 and 13 with irrigation is an ideal condition for heat transfer, vapor condensation and solid particle deposition. The temperature of the gas being removed through the branch pipe 12 can reach 60 ° C or lower.

Heat generator "Ryazan-2" is a highly efficient and environmentally friendly device and can be used for heating, hot water and steam supply in the immediate vicinity of the consumer.
