โœฆ Synopsis


A study of the flow and particle heating characteristics of a laminar entrained flow reactor used for experiments on the devolatilization and combustion of coal is presented. Flow visualization showed that proper inlet design and operating conditions are essential to prevent dispersion of coal particles and ensure uniform treatment conditions for all particles. Results of a finite difference model of the gas flow and temperature fields as well as particle motion and heating are discussed, and recommendations made for the design and operation of entrained flow reactors. It is concluded that an accurate model of the reactor flow field is essential for extraction of meaningful reaction rate data from experiments in the reactor.

Simultaneous SOz and NO, reduction in flue gas by the dry furnace sorbent injection process was simulated with an entrained-flow reactor. Several ammonium salts as well as urea were tested. Urea was found to give the highest NO, removal efficiency. By using urea-limestone sorbent, > 90% SOa removal

The effects of reaction temperature, oxygen/coal and steam/coal ratios and residence time on coal gasification performance in entrained flow were determined by means of a drop tube reactor (0.05 m.i.d. x l.Om high).

A small scale test apparatus is developed to measure the relative tendencies of different coals to agglomerate in dilute phase reactors with entrained flow and under conditions of flash pyrolysis. The important variables influencing agglomeration for a given coal are its feed rate and the temperatur
