Abstract
Description
- 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.
- In the known gas ceramic radiators, among others, by Schwank or Solgaz, the air is sucked into the gas duct and then the generated mixture flows into the chamber from which it comes out onto the ceramic plates surface where it is burned.
- 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.
- According to the invention 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. On the gas connection, 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.
- Owing to overpressure in 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.
- At an operating temperature of the emitter increased up to 1000 - 1200°C, the radiation efficiency of the device is 10% higher as compared with the device operating at a temperature of 800 - 1000°C.
- Moreover, 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.
- As an advantage 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.
- The subject of the invention is presented in the drawing, where Figure 1 shows the layout of the shield, emitter with the ceramic plates and housing of the supply system, and 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 ofceramic plates 2 with small holes . Theshield 3 and supply system in thehousing 4 are connected with thebody 1. The supply system consists of thegas connection 5 to feed gas to theelectric valve 6, which through thescrew joint 7,gas nozzle 8 placed in theport 9 andair 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 themain body 1. The mixture flows to the surface of theceramic plates 2 through small canals; where the electronically controlledigniter 14 initiates ignition. - The
electronic control system 13 controls the operation of theelectric valve 6,fan 12 and igniter 14. - In case of any voltage failure or break in gas supply, the radiator is automatically switched off.
