Study On The Optimal Component Ratio And The Combustion Characteristic Of The Biomass Compound Coal

BCC(biomass compound coal) as the new type energy, is the valid path for alleviating the energy crisis, making use of a recycle energy resource efficiently, protecting environment and solving combustion shortage of the traditional industry briquette. At the present time, it isn't enough to the research of BCC thoroughly, and the contents also are certainly some localization. Thereby, there isn't a unified direction for the sake of industry production toward the optimal component ratio and combustion characteristic of BCC. The purpose of thesis is to research the optimal component ratio and combustion characteristic of BCC, then find out some regulation that can apply to the industry production for BCC.According to the above-mentioned purpose, this thesis mainly carried on following several researcheses:â‘ BCC is composed of anthracite coals from Qitaihe as the raw coal, haulm of the corn as the biomass and loess as the cementing agent. Taking the volatile matter and the calorific capacity as the experimental targets, consulting the former research of the optimal component ratio for BCC, combining the characteristics of the oneself of " Optimal Experiment Design and Analyse " method, adopting the quadratic regression and correct meet combination design with two factor in order to study the optimal component ratio of BCC, experimentation obtained the regression equation between the experimental targets and components and obtain the optimal component ratio.â‘¡For the sake of comprehending the combustion characteristic of BCC deeply, Thermegravimetry Experiment is carried on under the pure oxygen atmosphere and temperature rise controlled by program. It get the correlative trial datum that are composed of quantity, temperature and time, draw the Thermegravimetry curve(TG) and the differential coefficient Thermegravimetry curve( DTG),and obtain characteristic parameter of BCC. The result manifestation that it is very good for combustion of BCC, and surpass the traditional industry Briquette.â‘¢In allusion to the Thermegravimetry Experiment, analyze the combustion...
