摘要： 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.

摘要： 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.

摘要： A tubular furnace uses a fluid to be heated which is prevented from coking or a heating tube which is prevented from burning. Heat is provided through a smaller heat transfer area and problems of corrosion at low temperature of the heating pipe in the tubular furnace due to sulfur content in the fuel are solved, to thereby achieve a high efficiency. A coil path(3) is divided into a plurality of zones(2a,2b,2c,2d), each with at least one regenerative-heating-type alternate combustion system(4). The system supply combustion air to burners(5,6) through regenerative beds(7,7) and the discharge of combustion gas therefrom. Combustion is independently controlled in each zone to create a desired heat flux pattern such that a boundary layer temperature of the fluid to be heated in the zones(2a,2b,2c,2d) of the coil path(3) is lower than a coking temperature or lower than an allowable maximum temperature to be determined by the material of the heating pipe.

摘要： The present invention relates to a deodorizing system for reducing the size of a facility and realizing the thermal efficiency much higher than the prior art, wherein a deodorizing furnace 1 is connected with thermal equipment 8 which uses a heated gas current as a heat source through an out-of-furnace circulating path 4 in order to circulate combustion exhaust gas in a deodorizing furnace 2 which has been used for incineration or thermal decomposition of odor components. When the combustion exhaust gas passes through a regenerative bed 5A or 5B on an intake side of the out-of-furnace circulating path, a part of sensible heat of the combustion exhaust gas is recovered in the regenerative bed 5A or 5B and the combustion exhaust gas is turned into a heated gas current that can be used in the thermal equipment 8 to be then supplied to the thermal equipment 8. Subsequently, upon completion of a predetermined process in the thermal equipment 8, the combustion exhaust gas is again made to have a high temperature and returned to the deodorizing furnace 2 by utilizing the recovered heat in the regenerative bed 5B or 5A on an outlet side of the out-of-furnace circulating path.
