  • COMPARISON OF PROCESS FLOWS: FLUID BED COMBUSTOR AND GLASSPACK®

    PURPOSEThe purpose of this document is to present the assumptions and calculations used to prepare Minergy Drawing 100-0204-PP00 (attached). The volumetric flows for both a fluid bed combustor (FBC) and Minergy’s patented GlassPack® closed loop oxygen enhanced combustion process are compared on this drawing. In this drawing, process flows are illustrated by scaling the width of the flow arrows ...

  • Techno-economic evaluation of revamping of coal-fired power plants in India

    A techno-economic feasibility study has been conducted to investigate the revamping of two 32 MWe Pulverised-Coal (PC) boilers with a number of firing options. The options investigated were: (1) conventional PC revamping, (2) replacement with a new PC boiler, (3) PC to Circulating Fluidised Bed (CFB) revamping, (4) replacement with a new CFB boiler, and (5) Bubbling Fluidised Bed (BFB) revamping. ...

  • Characterisation of LD slag of Bokaro Steel Plant and its feasibility study of manufacturing commercial 'fly ash–LD slag' bricks

    The aim of this study is to couple several analytical techniques in order to carefully undertake physical, chemical and mineralogical characterisations of LD steel slag to determine its feasible utilisation in commercial brick manufacturing. The characterisation results of LD slag showed that the pH and electrical conductivity of the samples were very high indicating high percentage of lime ...

  • Renewable fuel and energy production solutions reduce your total cost of ownership – Case Study

    Biomass represents a fastgrowing solution for renewable fuel, which can help reduce the need for foreign oil and provide an environmentally-friendly alternative for energy production. Typical biomass sources include switchgrass, hemp, wheat straw, corn stover, woody materials, and sugarcane tops. It is no wonder why biomass is capturing so much market interest as a replacement for coal in energy ...

  • Biochar: forgotten agricultural nostrum

    What is biochar?  The new multifunctional products are in good request nowadays. One of such innovations is Biochar. This type of charcoal is manufactured using the low-temperature continuous pyrolysis equipment. The raw material for the recycling process is biomass (agricultural and other biological waste). Biochar origins (Terra ...

  • Pyrolysis

    Introduction: Pyrolysis is formally defined as chemical decomposition induced in organic materials by heat in the absence of oxygen. In practice, it is not possible to achieve a completely oxygen-free atmosphere; actual pyrolytic systems are operated with less than stoichiometric quantities of oxygen. Because some oxygen will be present in any pyrolytic system, nominal oxidation will occur. If ...

  • Biomass energy outlook

    Over the last three or four weeks, my newsletter, Burning Bio News, has been oddly extreme. Timothy Searchinger, Princeton University, is churning out more antibiofuel hearsay. Dennis Avery, Hudson Institute, was in the news again putting a counter-spin on climate change. The U.S.EPA released its proposed rule for regulation of Greenhouse Gases (GHG) that includes industrial facilities that emit ...
