2.TECHNICAL MEASURES FOR CONTROLLING SMOKE POLLUTION BY AERATION IN GAS MAKING SECTION
3.After technical renovation the systems for gasification sewage and heat power ash effluent achieve closed-circuit circulation, so as to accomplish zero discharge of the gasification and heat power sewage.
4.Aimed at the technical process of coal gasification reactors production, a suit of monitoring software of the host computer is designed.
5.This paper illustrates the temperature at the aerification layer of the intermissive gas-generating furnace, realizing real-time temperature measuring and control by LabVIEW. The system can reduce the workers’ difficulty and intensity and improve their efficiency when they are fulfilling real-tine control over the state of the gas-generating furnace.
6.The use is presented of the bridge dredger in the treat-ment of sludge in the circulating water for gasification, and some sugges-tions for its use are offered.
7.Based on the gasification process of Lurgi gasifier,this paper describes the features of temperature elevating of the gas exit and/or ash lock and analyzes its reason,then summarizes the measures taken to avoid its happenning.
8.Gas production by burning small granular coke(o.d. 515mm)with UGI 3.0 m gas furnace was described. The utilization ratio of coke was improved from 72% to 83.2%.
9.The integrated system of smelting reduction ironmaking-gasolinesynthesis-electric- ity generation, in which the coal gas produced inthe ironmaking module is first cleaned and then used as the fuel for theelectricity generation module or raw material of the gasoline synthesismodule, can resolve the problem of utilization of tail gas in thesmelting reduction ironmaking and the large investment of gasificationin the integrated gasification combined cycle and gasoline synthesis.Taking efficiency, scale and product structure into consideration,the processes of the two-stage smelting reduction ironmaking-combined cycleelectricity generation with coal gas, the two-stage smeltingreduction ironmaking-steam cycle electricity generation with coal gas,the one-stage smelting reduction ironmaking-combined cycleelectricity generation with coal gas, and the one-stagesmelting reduction ironmaking-gasoline synthesis with coal gas-steamcycle electricity generation with tail gas are techno-economicallyfeasible and have the promise of being industrialized.
10.The newly made instrument can he used to expel polluted air from the workshop without any noise.
