The integration of an electricity production expansion turbine into the production line and the use of residual gas heat in the turbine cycle can reduce production costs. The article assesses two possible solutions for the integration of the expansion turbine into the technological line, namely with an open and closed working cycle using various gaseous media. In both cases, the proportion of the energy usable for electricity generation in the expansion turbine cycle has been calculated along with the possible fuel savings in the rotary kiln by using combustion air preheated to a high temperature by the residual heat of the gas from the turbine gas cycle.","PeriodicalId":36809,"journal":{"name":"Paliva","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49443207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The water content and calorific value of the wood chips were slightly lower than that of the wood pellets. The content of volatile combustibles and the elemental composition of the two compared energy raw materials did not differ significantly.\u0000On the contrary, significant differences were found in herbal pellets (from winter wheat straw, winter rye straw and from whole triticale) produced by the identical process. It was shown that both the plant material and the addition of 3 wt. clay flours (binders) affect their parameters. For example, the proportion of fine material by the addition of a binder was significantly reduced in rye (to 0.17% by weight) and triticale pellets (to 0.04% by weight). On the other hand, the disadvantage of adding clay flour as a binder additive is the increase in the ash content, which reduces the calorific value of the pellets. The heat of combustion of pellets made of wood materials was about 2.5 MJ / kg higher than that of herbal pellets. Combustion of pellets from the three types of herbs monitored produces more emissions of chlorine and nitrogen oxides contaminants than wood samples relative to wood samples. The chlorine content in ashes from herbal pellets compared to ashes from wood materials was about 50 times higher. The nitrogen content in the compared raw materials was about 5–15 times higher for herbs.","PeriodicalId":36809,"journal":{"name":"Paliva","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46939789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pure steam was used as a gasification agent at a ratio of 0.87 kgsteam /kgfuel, db. Calcite with mainly CaCO3 in compositions was used as bed material for the reactor. Significant H2 content was determined with high quantity of CO2 and CH4 in product gas, while CO level was relatively low. Due to the considerable sulfur and nitrogen contents of this fuel, values of the impurities NH3 and H2S in the producer gas was detected. It is also shown that the majority of sulfur was released in the gasification zone and, therefore, no further cleaning of the flue gas was necessary.
