In thermal power plants, coal-storage-yard structures play a major role in the production of power. Coal storage capacity is limited by the design level. If the design limit is exceeded, the reinforced concrete (RC) coal storage structure may undergo deterioration with varied cracking patterns and ultimately collapse. Through quick, early observations, engineers, construction managers, and others may be able to avoid major structural disaster and the associated risk to human life. Structural problems could cause the entire plant to shut down, and the down time may cost more than additional coal storage; thus, repair and rehabilitation has to be approached with cost-effectiveness in mind. The cause of the distress and failure mechanism of the actual damaged RC frame structure are evaluated and analyzed in this paper. The analyses are carried out using finite-element analysis with real life loading and other conditions, and based on the analysis, relatively economical rehabilitation strategies using structural steel members are proposed. During this process, it is suggested that the existing distressed and failed RC members be replaced with the proposed structural steel members under the supervision of the presiding engineer. © 2015 American Society of Civil Engineers.

Solar Energy | Year: 2015

In India, continuous production of electricity and sweet/potable water from Solar power and desalination plant plays a major role in the industries. Particularly in Carbon black industry, Solar power adopts Solar field collector combined with thermal storage system and steam Boiler, Turbine & Generator (BTG) for electricity production and desalination plant adopts Reverse osmosis (RO) for sweet/potable water production which cannot be used for long hours of power generation and consistency of energy supply for industrial processes and power generation cannot be ensured. This paper presents an overview of enhanced technology for Solar power and Desalination plant for Carbon black industry making it continuous production of electricity and sweet/potable water. The conventional technology can be replaced with this proposed technique in the existing and upcoming industries. © 2015 Elsevier Ltd.

Membrane Water Treatment | Year: 2015

In India, recycling of treated effluent plays a major role in the industry. Particularly in copper industry, recycling techniques for treated effluents adopt conventional technologies which are not energy efficient and recovery of high quality process water, free flowing salts and sludge's is very low. This paper presents an overview of enhanced modern technology for treated effluents in copper industry making it more efficient with high recovery of high quality process water and free flowing salts. Life cycle cost (LCC) would be 15-20% lower than the conventional technologies. The conventional technology can be replaced with this proposed technique in the existing and upcoming copper industries. © 2015 Techno-Press, Ltd.
