Evidence suggests an increase in the risk of common and serious diseases in users who are exposed to biomass smoke. To minimize the harmful effects associated with cooking, designing and creating a more efficient cook stove has been proposed. In conjunction with teams P11461 and P11462, P11451 will be building on P10451’s previous work to develop RIT’s capabilities to test cook stoves. Problem Statement: The mission of P11451 is to define test methods and document testing procedures relevant to the Haitian customer needs. Also, by conducting the Water Boil Test (WBT), the test stand should be able to benchmark the RIT stove against other existing stoves. The testing process needs to have more repeatable and accurate results than the previous project team. Testing methods should quantify the stove’s fuel efficiency, cooking performance, and emissions in engineering terms. Objectives/Scope: 1. Create and document standardized test procedures for the test stand. 2. Modify existing test stand to deliver repeatable as well as accurate emissions and efficiency results. 3. Benchmark created RIT stove against published cook stove standards. Deliverables: 1. Functioning test stand 2. Documented testing procedure 3. Documented benchmark results against published results 4. Produce results for project teams P11461 and P11462 Expected Project Benefits: To deliver a test stand along with documented testing procedures that future MSD teams can use to benchmark existing stoves and confidently compare RIT stove performance with published data. Core Team Members: Huseyin Zorba – Project Manager Phillip Amsler David Sam KGCOE MSD Page 2 of 31 Technical Review Strategy & Approach Assumptions & Constraints: The team must review all previous work done during last year’s stove project and improve on existing testing protocol. Expected results from a standard WBT such as efficiency, carbon monoxide, and particulate matter must be accurate and repeatable through the use of electronic sensors and standard test procedures. All laboratory equipment and test standards must met RIT EH&S Laboratory Safety Standards. OSHA Laboratory Standards can be found in 29 CR 1910.1450. Issues & Risks: Obtaining accurate particulate matter results while meeting budget Health risks associated with cook stove testing and emissions Obtaining parts and hardware that can be integrated with current system Action List Item # Description A001 Start to Develop & Document Test Procedure A002 Coordinate testing with other teams A003 Add Figures & Pictures to the Procedures A004 Correction on the Description for the Flow rate A005 Differentiate the user as “Untrained” and “Trained” A006 Have a Distinct Concept Expectations Catch mistakes and improve design.

  • From Biomass Towards Syngas 1 Introduction
    TRANSACTIONS OF THE INSTITUTE OF FLUID-FLOW MACHINERY No. 127, 2015, 63–89 DARIUSZ KARDAŚ1 From biomass towards syngas The Szewalski Institute of Fluid-Flow Machinery of the Polish Academy of Sciences Fiszera 14, 80-231 Gdańsk, Poland Abstract The article presents and overview of selected physical and chemical issues relating to biomass gasification. It also includes the history of the development of thermal wood treatment technology, with particular attention paid to Polish threads. Basic physical and chemical properties of biomass are discussed, using wood and straw as representative examples. Main types of gravitational gasifying reactors are presented, along with the analysis of basic mechanisms of homogeneous and heterogeneous chemical reactions in the reactor bed. The equation of motion of bed particles is derived based on particle volume changes caused by pyrolysis and surface reactions. Keywords: Biomass; Pyrolysis, Gasification; Bed subsidance, Reactions 1 Introduction Wood gasification is not a new technology. Archaeological research has re- vealed that its version consisting in wood carbonisation was already known as early as several thousand years ago. A basic goal of the wood carbonisa- tion technology was to produce charcoal, which until the nineteenth century was the main raw material for various economy sectors. Charcoal was used in smelters and forges, as its high combustion temperature, above 2000 oC, by far exceeded the melting point of iron, which is slightly higher than 1100 oC. Charcoal was also used in medicine and gunpowder production. 1E-mail address: [email protected] ISSN 0079-3205 Transactions IFFM 127(2015) 63–89 64 D.

  • Iron, Steel and Swords Script - Page 1 Pyrolysis of Pretty Much All Organic Stuff (Including You) Thus Can Be Done for Several Purposes
    History of Carbon Introductory Remarks Carbon compounds are rather prominent on this planet. They are called organic compounds and are found in abundance in what's called "biology". For example, the following three simple and well-liked molecules contain plenty of carbon (C): C2H5OH. Chemical short-hand for the (ethylene) alcohol found in beer, red wine and other important liquids. C6H12O6. Known as starch and found, for example, in pasta and other necessities of life. C6H10O5. Sweetening life because it's (glucose) sugar. There are a hell of a lot (million, billion, trillion, whatever you like) more organic molecules around, including DNA and other rather complex stuff. Pretty much all of them could be used to make carbon. Advanced We also have carbon compounds in gases like the carbon dioxide (CO2) that provides the fizz in soda and changes the climate, or carbon monoxide (CO) that kills you and allows (carbon) smelting of metal ores. Elemental carbon, however, is not so easy to find. Ancient humans pretty much only encountered it in the cinder, soot, and charcoal leftovers found after some tree was hit by lightning and burned down, or after they started to make fire themselves on a regular base (some 300,000 to 400,000 years ago; possibly even more than 1 Mio years). Whatever black stuff remains after a careless burning of organic material is very dirty carbon. The greyish stuff is ash, consisting of inorganic "salts". The name carbon comes from the the French "charbone", which in turn came from Latin "carbo", meaning "charcoal". In German the name is "Kohlenstoff" which literally means "coal-stuff".
