    摘要： Burners, such as all kinds of fuel oil, gas and powdered coal, have combustion chambers for stabilizing combustion and air distribution. The invention discloses a forced reversal combustion chamber (3), which comprises a combustion chamber body, configured as a hollow cavity which is similar to a arcing shape formed by folding fingers towards palm and symmetrically configured around center of palm; a plurality of swirl vanes for delivering combustion air into the combustion chamber (3), correspondingly provided on interior side of flame outlet end of the combustion chamber (3); in the middle of inner end of the combustion chamber (3), a fuel nozzle (2) is provided, which inserts into interior wall of the combustion chamber (3) and outlet of which extends through the interior wall of the combustion chamber (3); outlet end of the combustion chamber (3) after mixing air and fuel is flame outlet. The forced reversal combustion chamber (3) of the invention could overcome defects in the prior art, such as bad flame stabilization, low burn-off rate of fuel and poor environmental protection property, and achieve advantages of good flame stabilization, high burn-off rate of fuel and good environmental protection property.

    摘要： A combustion chamber may include a first surface and a second surface interconnected by a wall forming a chamber having a central axis. The first surface may define an exhaust opening and the second surface defining a pilot opening, wherein the exhaust opening and the pilot opening align along the central axis. A plurality of inlet ports may be configured to deliver air to the chamber. A plurality of fuel ports may be arranged on an inside of the second surface to deliver fuel to the chamber. The air flow from the inlet ports and fuel from the fuel ports may oppose each other to create a vortex of product proximal to the second surface.

    摘要： Areliable and cost-effective boiler equipped with a sound air supply nozzle which enables the following is provided: even when there is a gap between the nozzle provided in a through hole communicating with the interior of a furnace and the through hole, a strong swirl flow along the inner surface of the furnace wall can be formed; and burnout due to radiant heat can be suppressed. The air supply nozzle has the through hole in the furnace wall comprised of a water pipe, the nozzle supplying air is inserted into the through hole, and there is the gap between the nozzle and the through hole. The air supply nozzle is so configured that the position of the tip of the nozzle is located at a distance of 0.8 times the nozzle inside diameter or more away from the furnace wall inner surface and a tangential velocity component is given to gas jetting out of the nozzle.
