Abstract: The mineral means that coal its differ from the other minerals due to the different properties and heterogeneity character basically coal is divide four category i.e peat, bituminous, lignite and anthracite ‘Coal’ is one of the primary sources of energy accounting for about 80.7% of coal production for the total energy consumption in the country. India has some of the largest reserves of coal in the world. Indian coal has high ash content and low calorific value. However, with the present rate in India where approximately 52% primary commercial energy is coal dependant coal India alone meets to the tune of 40% of primary commercial requirement and commands 74% of the Indian coal market and its feed 82 out of 86 coal based thermal power plants in India, in accounts for 76% of total thermal power generating capacity of the utility sector and supplies coal at price the discounted to international prices, reserves coal likely to last over 90 years. The energy derived from coal in India is about twice that of energy derived from other sources, where energy derived from coal is about higher than energy derived from oil. Country produce electricity using oil, coal solar, wind and they import coal like the country Australia, China, Indonesia &South Africa. The Odisha, West bengal, Assam, Bihar, Jharkhand, Chhattisgarh, Madhay pradesh, Andhra pradesh, Gujarat and Tamil nadu are the coal reserve states in India. Coals are used regularly for generation of heat but due to globalization the proper assessment both the quality and quantity is most important for modern industry and environmental conservation. In this research we used different instruments and for the spectroscopic analysis used FTIR and ESI-MS and express the difficulties are going on and how it direct impact to economy and environment.Abstract: The mineral means that coal its differ from the other minerals due to the different properties and heterogeneity character basically coal is divide four category i.e peat, bituminous, lignite and anthracite ‘Coal’ is one of the primary sources of energy accounting for about 80.7% of coal production for the total energy consumption in the country.

Abstract: The objective of this study is to obtain, by means of a new design of the pipe which transports the hot air from the solar collector to the drying chamber, a uniform temperature inside the drying chamber so that the product to be dried deposited in all trays is evenly dehydrated. Outdoor drying experiments of agricultural products were carried out to test the thermal performance of a natural convection solar dyer constructed. Almost all the products were dehydrated in a single day. Since the quality of dried product depends significantly on the temperature of the drying process passive thermography -was used to monitor the product temperature during the drying process. The thermal images reveal that under climatological normal conditions the temperature gradient is 1-3°C among the apple slices placed in trays; the existing moisture in the surface of the specimens is homogeneously released and the maximal temperature attained by the product is less than 40°C when the irradiance is 1000 W/m2 and the average temperature of the hot air in the drying cabinet is 55°C.Abstract: The objective of this study is to obtain, by means of a new design of the pipe which transports the hot air from the solar collector to the drying chamber, a uniform temperature inside the drying chamber so that the product to be dried deposited in all trays is evenly dehydrated.
