Correlation Between Central Receiver Size and Solar Field Using Flat Heliostats

In Central Receiver Systems (CRSs), thousands of heliostats track the sunrays and reflect beam radiation on to a receiver surface. The size of the reflected image and the extent of reflection from the heliostats are one of the important criteria that need to be taken into account while designing a receiver, since spillage losses may vary from 2 to 16% of the total losses. The present study aims to determine the size of an external cylindrical receiver, such that the rays reflected from all the heliostats in the field are intercepted. 

Challenges and opportunities for Solar Tower technology in India

Solar Tower technology has gained considerable momentum over the past decade .Unlike the parabolic trough, Solar Tower has a lot of variants in terms of type of receivers, working fluids, power cycles, size of heliostats, etc .Most of the literature available on this technology does not address in great depths, details of various parameters associated with tower technology.The role and significance of this technology is brought out in the context of the Jawaharlal Nehru National Solar Mission (JNNSM) in order to achieve grid-connected solar power.

Construction and Demolition Waste Utilisation for Recycled Products in Bengaluru: Challenges and Prospects

The study aims to contribute towards creating an ecosystem of CDW recycling in Bengaluru (formerly Bangalore). The analysis explores the status and future outlook of CDW generation and disposal in the city through a combination of literature review, site visits and primary surveys. It reviews the policy landscape and regulations around CDW management and disposal formulated by the municipal authorities.
