High Temperature Drop Tube Reactor (DTR) - MTD

Design and Development of High Temperature Drop Tube Reactor System by CPRI First time ever in India First time ever in India, CPRI has successfully designed and developed a high temperature (1500°C) Drop Tube Reactor for studying the combustion characteristics of coals and coal blends at CPRI as a part of the R&D consultancy project sponsored by NTPC-NETRA Greater Noida. This indigenously developed system was installed and demonstrated to NTPC-NETRA.

The growing demand in power and the concern towards the emission from coal fired power plants, the research on coal is on high priority to improve the efficiency of the boilers and reduce emissions to zero level. The high temperature DTR system simulates the heating rates as prevailing in pulverized coal boilers and assessment of the combustion behavior of coal particles in controlled conditions. The combustion reactivity, pyrolysis characteristics and ash deposition mechanisms of coal and coal blends can be studied using this system at different combustion conditions. The data obtained from DTR system is immensely helpful in optimizing the operating conditions of the boiler, while utilizing specific coals/coal blends for achieving improved boiler efficiency and lowering emission. The efficiency of the additives intended for reducing slagging/fouling conditions can be assessed at laboratory level using DTR. The DTR also provides vital inputs for CFD simulations for designing new boilers and retrofitting old boilers.
