NTPC to buy machinery to convert farm waste into power

State-run NTPC has floated a tender to buy plant and machinery to convert farm waste into pellets that will ultimately be blended with coal to produce power.

The power giant seeks to identify vendors for supply and installation of plant and machinery for torrifaction of farm residue and manufacturing of pellets.

Torrifaction is a process in which biomass is subjected to high temperature in absence of oxygen to convert it into a coal-like material. Besides increasing calorific value, reducing moisture content and making biomass brittle and grindable in normal coal mills, it also leads to reduction in transport component of torrified biomass due to increase in calorific value of biomass after torrifaction.

According to a moneycontrol.com report, NTPC aims to replace coal with secondary fuel such as paddy straw and other farm waste-based briquettes and pellets to the extent of 5 per cent to 10 per cent of daily consumption at plants wherever this machinery can be installed
