摘要： PROBLEM TO BE SOLVED: To recover waste heat from exhaust gas involving a large quantity of water, and hence improve a heat transfer coefficient of a heat transfer surface in a heat exchanger and further suppress a corrosion phenomenon of a heat transfer pipe. SOLUTION: An exhaust gas waste heat recovery heat exchanger comprises a trunk structure 1 including on an upper portion thereof an exhaust gas exhaust outlet 8 communicated with a flue, including therein heat exchange heat transfer pipes 2, 2... and a water droplet removal filter 4, and including in a bottom thereof a porous plate 3, and comprises an outer trunk structure 1a including a bottom thereof communicated with the trunk structure 1 and including in a side thereof an exhaust air stream inlet 6 communicated with a boiler. In the heat exchanger, a water pool layer is formed in the trunk structure 1 and in a bottom layer portion of the outer trunk structure 5, and the water is pushed up to the heat exchange heat transfer pipes 2, 2... with the aid of exhaust gas to form a water fluidized layer. Further, a bypass pipe 8 is coupled with an upper portion of the outer trunk structure 1a for directly feeding part of the exhaust gas flowing from the exhaust air stream inlet 6 to the exhaust gas exhaust outlet 8, and further for joining high temperature exhaust gas to the exhaust gas brought into a water saturated state after passage through the water fluid layer and the water droplet removal filter 4, and reheating those gases and feeding them to the flue.

摘要： PROBLEM TO BE SOLVED: To provide a drier which recompresses produced steam with a compressor so as to recover the latent heat of evaporation while drying a solid including moisture, and evaporates the moisture with the heat of condensation and dried the solid. SOLUTION: This drier is composed of a kiln body 1 for heat exchange and a steam compressor 2, and sealing devices are constituted at the inlet and outlet of the kiln body for preservation of airtightness of the inside of the body, and rotary valves, etc., for sealing are installed at the charge port and the discharge port of raw material, too. The material dumped in the charge port is dried by the steam passing inside an electrothermic tube, and the evaporated steam is compressed through a steam compressor 2, whereby it comes to high temperature and high pressure, and the latent heat of the stream is completely recovered by carrying out heat transfer by the temperature difference.

摘要： PROBLEM TO BE SOLVED: To compress steam by adding the speed energy of steam exhausted from a turbine by an ejector effect. SOLUTION: In case of a centrifugal type compressor, turbine blades 7 and 7 are set in the radial direction at the rear surface of the blades, and a guide vane 4 is set at the rear side of the turbine final end, so as to compose to make the steam exhaust direction the same. In the case of an axial flow type compressor, turbine blades 7 and 7a are set at the rear side in the radial direction of the blades 7 and 7a, guide vanes 8 and 8a are set at the rear side of the turbine blades, and the direction of the steam exhausted from a steam compressor, and the direction of the steam exhausted from a steam turbine, are made the same.
