    • A boiler is provided with a radiation heat transfer section in its combustion chamber, which has therein, at least one regenerative-heating burner system including a pair of burners each with a regenerative bed. The burners receive combustion air and exhaust combustion gas which passes through the regenerative beds. Combustion is alternately effected in one of the burners and combustion gas is passed into the other burner, and exhausted through the corresponding regenerative bed of this other burner. Surplus thermal energy which is not completely consumed in the radiation heat transfer section is recovered in the regenerative bed. Combustion air than passes through the heated regenerative bed to heat the air. The boiler temperature is kept flat across the boiler. That is, the temperature is kept almost constant across the combustion chamber. This is done by maintaining a high rate of forced supply of more than 60 m/s for the combustion air. Also, the combustion air is heated to above the ignition point of the fuel, that is, about 800.degree. C. These two factors increases thermal efficiency while reducing NO.sub.x emissions.
    • 锅炉在其燃烧室中设置有辐射传热部分,其中具有至少一个再生加热燃烧器系统,其包括具有再生床的一对燃烧器。 燃烧器接收通过再生床的燃烧空气和废气燃烧气体。 在其中一个燃烧器中交替地进行燃烧,并且燃烧气体进入另一个燃烧器,并且通过该另一个燃烧器的相应的再生床排出。 在再生床中回收在辐射热传递部中未完全消耗的剩余热能。 燃烧空气比通过加热再生床加热空气。 锅炉温度在锅炉上保持平坦。 也就是说,燃烧室内的温度几乎保持恒定。 这是通过为燃烧空气维持高达60m / s的高强度供应来实现的。 此外,燃烧空气被加热到高于燃料的点火点,即约800℃。这两个因素在降低NOx排放的同时提高了热效率。

    • A boiler has a radiation heat transfer section with opposite sides and boiler water tubes therein for passing boiler water to be heated by combustion gas in the radiation heat transfer section. The boiler water moves substantially in a selected direction in the radiation heat transfer section. A plurality of regenerative-heating-type burner systems are connected to the radiation heat transfer section. Each burner system has a regenerative bed and a burner. The burner systems are in pairs on the opposite sides of the radiation heat transfer section. A first mechanism supplies combustion air through the bed and to the burner of each burner system while a second mechanism supplies fuel to each burner system to form a flame that produces the combustion gas. A third mechanism causes the flow of air and gas to be changed over at intervals. Each pair of burner systems is controlled separately for defining a plurality of temperature zones in the radiation heat transfer section.
