TH16155A - A circulating platform-based reactor consisting of an external heat exchanger that is fed by circulating internally. - Google Patents

Abstract

The recirculating platform-based reactor consists of a bottom zone (3) with a fluidization grid (11), a primary and secondary air spraying device (12, 13), and a fuel feeder. (10), upper zone (2), platform which emits internal bubbles (22, 23) at the top of the lower zone (3) collects solid substances from internal circulation to the machine. The reactor is then delivered to the platform heat exchanger, which produces an external bubble that is closely connected to the reactor wall on the same level as the internal platform (22, 23). Let the solid substance enter the lower zone (3) after the heat exchange with the external fluid. The reactor has an uncomplicated frame and takes advantage of the external platform which causes the bubble while maintaining the normal pattern in the lower zone (3).

Claims (3)

1. One recirculating platform bed reactor consists of a lower zone (3) under conditions with a recirculating platform. And provide a grid For fluidization (11), the primary air spraying device (12) is below the grid (11) and the secondary air spraying device (13) above the grid (11), the reactor wall, which Surrounding the lower zone (3) has provided cooling pipes (4), the upper zone (2) operating under the conditions used. The circulating fluidized platform was surrounded by The reactor wall provided with a cooling pipe (4), a fuel intake device (10) into the bottom set (3), an external heat exchanger (18, 19, 20, 21) at least. The most one Consisting of a pedestal Where bubbles are placed against the reactor wall (1), the platform is fed with a solid substance which From the reactor and deliver the solid substance. Into the lower zone (3) after heat exchanging With the external fluid to heat up, the reactor has been It shall be characterized in that it consists of one or more internal foaming platforms (22, 23) installed in the top of the lower zone (3) on the surface of the reactor (1). Or more surface and is used to collect solid substances which fall down the upper zone wall (2) first and second to collect the substance. Solid, which comes from the reduction in gas velocity for Induction of a fluid passing through the platform which produces a bubble inside (22, 23), the ratio (S / S \ '\') of the perpendicular cross-section (S) of the upper zone (2) divided by the section. The perpendicular cross-section (S \ '\') of the lower zone (3) is leveled with the internal platform (22, 23) in the range 1.05 to 5, and with the external heat exchanger (18 , 19, 20, 21) were placed over the secondary air inlet (13) and return (9) and were fed with a solid substance from the platform, which made Resulting in internal bubbles (22, 23). The solids from the platform (22,23) will fall into the lower zone (3). 2. Reactor according to claim 1, make it characteristic Specifically, some external heat exchangers (20, 21) are used to regulate the reactor operating temperature. 3. Reactor according to claim 1 or claim 2, making it unique with the first change. Some external heat units (18,19) are used to regulate the temperature. Of whatever flows that are vapor that are heating up new in a radiator of Source of power using natural fuel
