In spite of very good potential for using biomass as a renewable source of energy the practice is in very early stage and limping. There are many factors which contribute their parts in making the process unsuccessful. The major ones are seasonality of the raw materials, shortfalls in logistics, absence of proved manufacturing systems, lack of skilled workers and very many technical factors. Considering technical factors for the screw type of briquetting the biomass, the life of the screw and the mould contribute the highest percentage of hindrance to the production process and hence the highest chance of improving the total productivity. A successful process of producing quality briquettes is very essential in using biomass as a viable and sustainable energy alternative. Most of the researches are going on finding the methods to improve the life of the screw and improving the production process. In this paper the experiments done in improving the life of screw, mould and total productivity due to their combination and the results obtained are discussed. It was found that the improvement in the amount of production is very much influenced not only by the life of the screw but also the life and quality of the mould which acts as the base on which the profile and performance of the screw stands.
Key words: biomass, briquette, productivity, sustainable energy
India is predominantly an agricultural country. Once the grains and other food items are harvested out a good percentage of the crop residues are used as animal feed, firewood and a lot of consumer products made to be sold in the market. In spite of these uses a high percentage of crop residues are still being burnt in the fields without an...

Essay on Biomass Briquetting Plants

- HUB AND SPOKES MODEL In this model we propose a two stage hub and spokes model consisting of a large scale biomass consumer like biomass power plant as the centre and it is surrounded by m number of briquetting plants. Each briquetting plant acts as a centre in turn and surrounded by n number of biomass collection centers. The biomass collection centers acts as buying agents and send the raw material to the biomass briquetting plants where they are stored, processed, packed and sent to biomass power plant....   [tags: environmental solutions, energy efficiency]

Productivity Improvement in Screw Type Biomass Briquettes Manufactoring by Planning Downtime

- ... The experimental details are given in table 1. Table 1 Experimental details for Eutectrode 700 coated screw The same kind of trials are repeated with screws coated with VAUTID 302 which is a tungsten carbide electrode and its coating increased life of screw to more than 10 hrs[10]. The same type of mould with Eutechtrode 700 was used in this trial but replaced along with the second screw replacement. Readings were taken for 4 trials to keep the total duration similar to that of first set. The next set of trials with planned stoppages was also conducted for 4 trials in the similar way and the readings tabulated....   [tags: ine, screw, process]

Alternative Energy Resource: Biomass Essay

- Biomass is a biological material derived from living, or recently living organisms. In the context of biomass for energy this is often used to mean plant based materials, but biomass can equally apply to both animal and vegetable derived material. Biomass is considered to be one of the key renewable resources of the future at both small and large scale levels. It already supplies fourteen percent of the world’s primary energy consumption. Growing Biomass is a rural, labor-intensive activity, and can, therefore, create jobs in rural areas and help stem rural to urban migration....   [tags: biomass, renewable resource, organic]

- ... A number of milling processes (ball milling, two-roll milling, hammer milling, colloid milling and vibro energy milling) can be used to enhance the enzymatic hydrolysis of lignocelullosic materials (Taherzadehand Karimi, 2008). The power necessity of this pretreatment is comparitively high. Considering, the high-energy requirements and the soaring energy prices, this process is not economically feasible (Hendriksand Zeeman, 2009).

Productivity Improvement in Screw Type Biomas Briquettes Manufacturing by Planning Downtime

- ... The heating process is needed to eliminate moisture and volatile matters and to melt the lignin content in the raw material which acts like a binder. The quality of briquettes produced justifies the use of skilled labor. Due to high wear rate of screw and mould particularly the screw which have very short life about 4 to 15 hrs [10] there are regular stoppages of production, reconstruction of tools and wastage of output.Research works are going on all over the world in designing compact briquetting machines, producing smaller diameter (35mm) briquettes [11] to make it suitable for gasification, improving the life of screw, using waste briquettes to heat the raw material and mould and to...   [tags: power, applications, densification]

Categorization of Biomass Material, Pollution Forming mechanism and Health Impacts in Developing Countries.

- Introduction Biomass energy is important renewable source of energy that is derived from either living or organisms that were in existence recently. This energy source is used in dual purposes; to be used directly with the process of combustion to produce heat or through indirect means after its conversion into different forms of biofuels. The focus of our project would be usage of Biomass energy through mainly combustion process in the developing world. In this region biomass is the primary source of domestic energy supplying approximately over 70% of the energy consumed (Ndiema, Mpendazoe and Williams, 1997)....   [tags: Biomass Energy, Renewable Source of Energy]
