Research proposal on biomass gasification technology
Gasification is a century old technology, which flourished quite well before and during world war II. The technology disappeared soon after when liquid fuel became easily available. The interests in the gasification technology have undergone many ups and downs in running century. Today, because of increased fuel prices and environmental concern, there is renewed interest in this century old technology. Gasification has become more modern and quite sophisticated technology. The advantage of this technology is decentralized energy conversion system which operates economically even for small scale .A gas producer is a simple device consisting of usually cylindrical container with space for fuel, air inlet, gas exit and grate. It can be made of fire bricks, steel or concrete and oil barrels. The design of gasifier depends upon type of fuel used and whether gasifier is portable or stationary. Gasifier alone itself is of little use. The complete gasification system consists of gasification unit (gasifier), purification unit and energy converter - burners or internal combustion engine.
Gasification is thermochemical process which converts biomass materials into gasesous component. The result of gasification is the producer gas, containing carbon monoxide, hydrogen, methane and some other inert gases. Mixed with air, the producer gas can be used in gasoline or diesel engine with little modifications. Based on the design of gasifiers and type of fuels used, there exists different kinds of gasifiers. Portable gasifiers are mostly used for running vehicles. Stationary gasifiers combined with engines are widely used in rural areas of developing countries for certain purpose including generation of electricity and running irrigation pumps. Technologies such biomass gasification which allows utilization of biomass fuel are of great importance. Furthermore, biomass gasification means incomplete combustion of biomass resulting in production of combustible gases, including Carbon monoxide, Hydrogen, Methane, CmHn, as the mixture is called pyrolysis gas that can be used to run internal combustion engines, and generate CHP. The production of pyrolysis gas called gasification, is partial combustion of biomass. The reactor is called gasifier. Water for gas cleaning and cooling can be used in a circulating way without environmental pollution after it’s treated througffh water treatment facilities such as sediment pond, and a little of making-up water required. - What is biomass within the gasification technology? - What is the process of the technology? And how long does it take to have biomass power materials? - What is the impact of gasification technology in the environment?
Methodology
The research study to be used is descriptive method. According to Creswell (1994) it intends to present facts about the nature and status of a situation as it exists at the time of the study. In addition, it also concerns with the relationships and practices that exist, beliefs and processes that are ongoing, effects that are being felt or trends that are developing (Best 1970). Therefore, it can be helpful in order to describe the current conditions and situations based on the impressions and perceptions of the respondents of the study (Creswell 1994). Surveys are the most common form of research method for collection of primary data (Commonwealth of Learning, 2000). One of its purpose is to describe, e.g., to count the frequency of some event or to assess the distribution of some variables such as proportion of the population of different age groups, sex, religion, castes and languages, knowledge, attitude and adaption of practices about particular issues, and other information of similar nature about the population (Commonwealth of Learning, 2000). A semi-structured questionnaire will be used for this study. In order to save money and time, interview and questionnaire can be done and send using new technologies such as e-mail and telephone. The data results of the study will be analyzed by determining their corresponding frequency, percentage and weighted mean.
