The invention concerns a device for extracting heat from gas, in particular combustion gas, containing dust and/or condensable substances to recover condensates, and comprising at least one heat exchanger (4) including a chamber (13) having a symmetry of revolution surrounded by a cooling envelope. The invention is characterized in that it comprises an orifice (9) for allowing through an agent for treatment surface of the inner surface of said chamber, said chamber (13) being moreover provided with at least a screw with helical pitch arranged coaxially in a tube (14).
摘要:
The invention relates to a heat accumulator (1) comprising a container (4) that is divided by a partition (5) into an inner core zone (6) and an outer annular zone (7), said annular zone containing a heat accumulator medium (8). The inner core zone (6) contains a heat accumulator medium (9) for forming a hot zone and heating means (10) are assigned to said core zone (6).
摘要:
This invention relates generally to the treatment of NOx in combustion flue gas. In certain embodiments, the invention relates to the use of a regenerative heat exchanger (RHE) to convert urea to ammonia in a side stream of flue gas. Ammonia and/or other urea decomposition products exit the heat exchanger,- are mixed with the rest of the flue gas, and enter a selective catalytic reduction (SCR) unit for reduction of NOx in the flue gas. The use o an RHE significantly improves the thermal efficiency of the overall process. More particularly in certain embodiments, the regenerative heat exchanger is a dual chamber RHE.
摘要:
A microminiature laminated heat exchanger for use in a cryogenic probe, and a method of manufacture. The heat exchanger has high and low pressure flow patterns (46, 48) etched into oxygen free copper sheets (42), with the flow patterns being tortuous paths promoting turbulent flow. The sheets (42) containing the flow patterns are bonded into a laminated assembly in the shape of a cylinder (28), with a high pressure inlet and a low pressure outlet in a first end, and a high pressure outlet and a low pressure inlet in a second end. The high pressure flow path lies alongside the low pressure flow path, with flow in the two paths being in opposite directions, to accomplish counterflow heat exchange. Substantial portions of the flow paths are either parallel to, or transverse to, the longitudinal axis of the heat exchanger, with the resuulting heat flow being essentially radial or axial, respectively.
摘要:
A heat exchanger for a regenerative thermal oxidizer (1) is described which includes at least one heat exchange column (5) provided with a bed of packing material (7) of specially shaped and sized particles, each particle being formed of a high temperature stable material and preferably having a cylindrical outer wall and internal reinforcing vanes extending from the cylindrical outer wall to the center of the particle.
