Definitions

  • the invention concerns a ceramic radiator supplied with gas to heat the industrial objects of a large cubic capacity.
  • the ceramic radiator operation consists in delivering heat by radiation of warmed-up ceramic plates.
  • the known and used radiators have a main body that creates a chamber equipped with ceramic plates to which an gas and air mixture is supplied, the emitter cover as an reflection shield and also a supply system for supplying the gas and air mixture, an igniter and an electronic control and regulation system.
  • the control and regulation system controls, among others, a gas outlet and a flame failure or a gas supply failure; as well as gas outflow and initiates the mixture ignition.
  • the heat radiation emitter in the gas radiators is made of ceramic plates having small canals and a specially prepared surface that are warmed up while burning the gas and air mixture on their surface.
  • the generated heat of combustion taken by the plates is given back in the form of infra-red radiation and a heat flux is directed to the specific places by shields with of a suitable shape and surface.
  • the temperature of the ceramic plates in the known radiators is from 800 to 1000°C.
  • the radiator according to the invention is characterized by a higher radiation efficiency, thus being more economic as compared with the known devices of this type.
  • the radiator consists of the main body with an emitter in the form of ceramic plates, a shield, a supply system, an igniter and an electronic control and regulation system.
  • the radiator contains a gas and air mixture supply system that provides optimum conditions for gas burning process that results in a higher temperature of the ceramic plates.
  • a mixer and a radial-flow fan are placed in the supply system to prepare the gas and air mixture of appropriate proportions and mix and feed it by 3 to 30 mbar overpressure into the main body chamber from which it comes out onto the surface of the ceramic plates and is burned.
  • the supply system contains an electric valve ended with a nozzle that is connected with an air inlet controller and next with a gas and air mixer and a fan chamber joined with the main body chamber.
  • Gas flows to the electric valve under influence of vacuum generated by a fan and is mixed with an air volume proportionally matched to gas volume and then pressed into the main body chamber.
  • the optimum matched homogeneous gas and air mixture coming out rapidly through small perforations on the surface of the ceramic plates is burned whereby the ceramic emitter elements reach a temperature of 1000-1200°C, thus generating an energy flux in the form of heat radiation.
  • the radiation efficiency of the device is 10% higher as compared with the device operating at a temperature of 800 - 1000°C.
  • the application of the fan with a variable rotational speed enables modulation of the heat power of the radiator stepless or step-by-step in the range of 50 to 100% of the maximum power.
  • the radiator has an additional piping for feeding air to the supply system from the outside of the heated object that is equipped with a filter to restrain mechanical impurities.
  • Figure 1 shows the layout of the shield, emitter with the ceramic plates and housing of the supply system
  • Figure .2 shows a general view of the radiator in the axonometric projection as well as the supply system elements.
  • the radiator contains the main body 1 in the shape resembling a cuboid, one side of which is an emitter made of ceramic plates 2 with small holes .
  • the shield 3 and supply system in the housing 4 are connected with the body 1.
  • the supply system consists of the gas connection 5 to feed gas to the electric valve 6, which through the screw joint 7, gas nozzle 8 placed in the port 9 and air inlet controller 10 is connected with the air-and-gas mixer 11 and the radial-flow fan chamber 12.
  • the fan 12 with a variable rotational speed blows the proportional homogeneous gas and air mixture into to the chamber of the main body 1.
  • the mixture flows to the surface of the ceramic plates 2 through small canals; where the electronically controlled igniter 14 initiates ignition.
  • the electronic control system 13 controls the operation of the electric valve 6, fan 12 and igniter 14.
  • the radiator In case of any voltage failure or break in gas supply, the radiator is automatically switched off.
