    摘要: A steam boiler (2) including a fire tube (21) and convection heating surfaces (22) is preceded by a combustion chamber (30) including a surface burner (34) for high excess air. The combustion chamber (30) and the fire tube (21) are internally thermally insulated (33). The combustion air supply opening (37) of the burner (34) is connected by way of a blower (40) with an exhaust air source (1). A fuel control valve (36) is controlled as a function of the boiler load. A plurality of heat exchangers (47, 48, 49) are incorporated in the flue gas channel (45) following the convection heating surfaces (22). The most upstream heat exchanger (47) is connected on the water inlet side by way of a pump (51) to the water chamber (23) and on the water outlet side by way of a baffle (53) to the water-steam circuit of the boiler (2). With this system it is possible to purify all of the exhaust air from the exhaust air source (1) over a broad boiler (2) load range.

    摘要: The combustion of fuel having a highly fluctuating thermal value is controlled to permit optimization of air supply and reduction of waste gas impurities. The fuel passes through a combustion chamber having a degassing and evaporation zone, a primary combustion zone, and a secondary combustion zone. Measurements are taken in the evaporation and degassification zone to determine the thermal value of the fuel. This is done by detecting the intensity of H.sub.2 O and/or CO.sub.2 spectra emanating from the fuel. The measurement results are utilized to optimize the combustion parameters. Such measurements are also made in the following zones in order to provide further control of the combustion process.

    摘要: A method and apparatus to batch de-coat the organics in metal scrap, and/or gasify the organics from certain types of waste material (including biomass, municipal solid waste, industrial waste, and sludge). The apparatus is suited for use on a batch tilting single entry rotary furnace of the type used to melt the metal scrap in the aluminum industry. The apparatus uses a burner in the tilting rotary furnace but does not necessarily melt the metal scrap. It preferably operates below the melting temperature of the metal scrap (
