Definitions

  • the invention relates to a device with which a large part of the waste heat is bound from the exhaust gases, which are emitted by boilers, internal combustion engines and other devices operated with liquid or gaseous fuels, so that water for feeding the boiler, the heating of rooms or to heat for other purposes.
  • the heat loss via the exhaust gases is 12-15% of the total amount of heat generated by the fuel.
  • Waste heat recovery devices which have a heat exchanger for exhaust gas / water, with pipes through which water is heated, which is heated by the surrounding exhaust gases before they escape into the atmosphere through the smoke exhaust.
  • the cylindrical outer shell (13) which is a specific device of this invention, since this shape facilitates the exhaust gas flow, the exhaust gases, which are emitted by a boiler, an internal combustion engine etc., enter through the inlet opening (1).
  • a heat exchanger (6) is installed, the weight of which rests directly on the floor without straining the structure of the shell.
  • the heat exchanger of this invention consists of three parallel rows of finned tubes (8) with fins (7).
  • the three rows of tubes (8) are a specific device of this invention because they facilitate access for cleaning all tubes of the heat exchanger.
  • the heat exchanger (6) is fed with cold water through the opening (10) and releases the warm water through the opening (11).
  • the exhaust gases enter through the opening (1) and, depending on the position of the rotary valve to change the flow direction (4), are guided by the two fixed valves (3) and (14) they flow in whole or in part more than once alternately to the two surfaces of the heat exchanger (6) and then exit through the opening (2) in the direction of the smoke vent.
  • the rotary valve (4) allows the flow of all or part of the amount of exhaust gas in the direction of the smoke outlet in a parallel or angular position to the heat exchanger.
  • the rotary valve (4) is moved by electric motors and its position is regulated by the thermostat (15) so that the exhaust gas temperature at the exhaust gas inlet (2) remains constant.
  • the water distributor (18) and the water reservoir (9) consist of the tube plate (12), which is provided with holes (16) in three rows, which are offset by one point, so that the two outer rows of pipes do not allow the inflow of exhaust gases to hinder middle row and also not free access for cleaning the pipes.
  • the finned tubes (8) are welded, which are flowed around by the flowing warm exhaust gases and which heat up and give off the heat to the water which circulates in them.
  • the flaps (17), which are located on the sides of the casing (13), can be used to clean the two surfaces of the heat exchanger (6), while the latter can be removed for repair by the flap (18).
  • Design variants of the newly developed device are the installation of several heat exchangers, as in Figures 3, 4 and 5, as well as an elliptical, rectangular or prismatic housing cross-section of the casing as in Figures 5 and 6.
