Hyderabad: Nalgonda is going to become the power hub of the state with installation of nine new thermal stations with a capacity of 6,800 MW, While they have to pay a heavy price if ultra-modern equipment which is not used in the construction of plants. And not less than 18,000 tonnes of ash will be generated everyday which has to be disposed of from the vicinity. MD of GENCO, Prabhakara Rao said the Telangana government is planning to use a mix-up of washed coal and imported coal which can reduce the ash content.
He said “The washed coal will reduce the ash by 15 per cent. But the cost of importing and washing the coal will increase the Budget”. The TSGenco has asked BHEL to install ultramodern boilers, that can combust more coal and produce less ash. And coal-fired power station boilers, industrial water-tube etc.
Venugopala Rao said “The fluidised bed combustion has emerged as a viable alternative and has advantages over conventional firing system and offers multiple benefits like compact boiler design, flexibility, higher combustion and reduced emission of pollutants but this has not been used here”.
Japanese emits eight tonnes of ash from every 100 tonnes immediately disposed of by sending them to cement companies, civil engineering works and land filling. Thousands of tonnes of ash have piled up or the last several months in nearly all the thermal stations.
The massive coal heaps harm to the environment and human health, the fly ash can affect mainly lungs and lead to severe bronchitis etc.
Dr Sasikala Rangaswamy said another problem is that the ash particles, inhaled by stray dogs, sheep, cattle etc can transmit it to humans leading heart, liver problems.
