Study on spontaneous combustion and environmental pollution in a coal storage yard

Abstract In coal fired power plants, Bituminous grade C is received through wagons from mines, unloaded, and separated as sized dust. Coal stored in stockpiles of around 22000 square metres that have been specified for storage. The size each stockpile 15’ length, 10’ width, height the temperature locality 38 °C, with summer temperatures reaching 42 °C. Spontaneous combustion occurred more than 90 times a six month time. More 75% area always has coal-stock since industries are far away mines 50 big furnaces use gas fuel. Raw dust higher sulphur content, very low onset temperature, highest volatile matter content. Hence, it undergoes spontaneous easily. fixed carbon higher, therefore its susceptibility to unstructured burning lesser contrast two new trials will calorific value. quality impact, while low-grade most responsible combustion, high-grade least susceptible warming. main indicators physical symptoms such odor, smoke, or heat sensation. polluted environments contain CO, CO 2 , CH 4 H 6 .
