摘要:
A temperature fluctuation suppressing device for a heating medium is provided which is capable of sufficiently suppressing temperature fluctuations of the heating medium at the time of supplying collected solar heat for steam generation, by suppressing the temperature fluctuation even if the temperature of the heating medium inevitably fluctuates with time. The temperature fluctuation suppressing device includes a heating medium mixer (10) provided on a heating medium supply passage (6) configured to supply a liquid heating medium to a heat exchanging device, the heating medium mixer (10) including: a heating medium passage forming member (29) having plural heating medium passages (30); an inlet member (91) allowing the heating medium to flow into the heating medium passage forming member (29) from the heating medium supply passage (6); and an outlet member (93) allowing the heating medium to flow out of the heating medium passage forming member (29) to the heating medium supply passage (6), the outlet member (93) being provided separately from the inlet member (91), whereby the heating medium continuously flowing into the heating medium passage forming member (29) through the inlet member (91) passes through the plural heating medium passages with time-lags to form respective streams, which are then joined together before flowing out through the outlet member (93).
摘要:
Steam quality at both outlets of an impact T-Junction is equalized by a static mixer having corrugated lamella plates immediately adjacent the inlet leg to the junction causing substantial homogenization of the liquid and vapor phases of wet steam entering the junction so that the steam exiting both outlet legs of the junction will have substantially the same quality as the steam entering the junction.
摘要:
In case of a steam generator having a circulating atmospheric or pressurized fluidized-bed combustion system, normally a fluidized-bed combustor, at least one separator, at least one fluidized-bed cooler connected to said separator and adapted to be fed by a part stream of the solids separated from the combustion and fluidization gases, and a waste-heat boiler pass are provided. In these elements feed water, evaporator and reheating surfaces are arranged. Together with a reheater heating surface at least one superheater heating surface is arranged in the fluidized-bed cooler and an adjustable by-pass line is associated to the reheater heating surface to allow a simple and quick control of the combustion while simultaneously offering a simple control of the outlet temperature of the reheater.
摘要:
An improved system of transferring heat energy from a high temperature fluid to a low temperature fluid is described. A countercurrent heat exchanger is employed in which heat transfer fluids undergo one or more thermodynamic transitions at various pressures by employing conventional heat exchangers having additional components. It has been determined that by employing this system of the present invention under a critical choice of design parameters, a substantially greater amount of heat energy can be transferred per unit area of the heat exchanger than was possible by conventional techniques.

A boiler apparatus for leading fluid from a plurality of upper walls (2) to (4) to a ceiling wall (7) through a ceiling wall inlet header (11), characterized in that a ceiling wall inlet mixing header (8) is installed between the plurality of upper walls (2) to (4) and the ceiling wall inlet header (11).
摘要:
An apparatus for dispersing the relative flows of a separated two phase flow using a nozzle positioned immediately downstream from a bend in a pipe. The inlet of the nozzle is adjacent an external wall of the pipe and the outlet of the nozzle is substantially on a longitudinal axis of the pipe. The dense phase is collected and transported through the nozzle back into the center of the pipe for uniform mixing and dispersion.
摘要:
A device is provided for dispensing a gas-liquid mixture which comprises a horizontal header with a plurality of inlet pipe connections for a gas-liquid mixture, the header having open discharge pipes connected thereto at the top thereof and containing vertical tubes within the header and provided with holes extending over the entire length of the tubes. The upper end of each tube extends into and in communication with a respective discharge pipe and the lower end is open. Preferably, the lower ends of the tubes are provided with teeth whose tips rest on the inner wall of the header.

An evaporator 10 for evaporating a liquid includes a plurality of harps 20 disposed within a duct or chamber such that a heated fluid flow 22 (e.g., heated gas or flue gas) passes through each successive row of harps 20 of the evaporator 10. Each of the harps 20 includes a lower header 24, a plurality of lower tubes 26, an intermediate equalizing chamber 28, a plurality of upper tubes 30, and an upper header 32. The lower tubes 30 are in fluid communication with the lower header 24 and extend upward vertically from the lower header. The upper ends of the lower tubes 26 are in fluid communication with the equalizing chamber 28. The upper tubes 30 are in fluid communication with the equalizing chamber 28 and extend upward vertically from the equalizing chamber. The upper ends of the upper tubes 30 are in fluid communication with the upper header 32.
