Última Design Modification of Conventional Wheat Straw Chopper CIGR Journal Ghafoor, Abdul. Agriculture has straight and indirect contribution to boost the economy of Pakistan. Wheat and paddy are among the major rotational crops of Pakistan. The straw management in combine harvested in wheat fields is a major problem. In the past the residual wheat straw in convectional harvesting was burnt in the field which resulted losses of 80% of Nitrogen, 25% P, 21% K and 4-60% S. To overcome this problem, locally available wheat straw chopper is used for cutting and collecting the wheat straw left behind the combine harvesters. These locally developed wheat straw choppers are heavy in weight having lower machine efficiency. A wheat straw chopper has been modified using locally available materials making it light weight and more efficient. The performance...

Ano: 2015 URL: http://www.cigrjournal.org/index.php/Ejounral/article/view/3031 Development and performance evaluation of indigenized flat plate collector water heater for domestic and industrial applications CIGR Journal Ghafoor, Abdul. Pakistan is facing severe energy crises from the last decade resulting daily electric blackouts from 8 to 12 h. The limited fossil fuel reserves and its environmental consequences have led to boost research and development of alternate energy resources. A huge amount of fossil fuels and electricity is being consumed for the generation of low to medium temperature heat energy for domestic, residential, agro-industrial and processing units. This low to medium temperature heat energy required can easily be fulfilled using solar collectors. This paper focus on the development of a flat plate collector using local infrastructure to reduce its initial cost. The collector consists of a window glass, absorber plate coated with black matt paint, copper tubes, inlet...
