High Efficient HRSG Waste Heat Recovery Steam Generator ASME Standard

Description

HRSGs consist of four major components: the economizer, evaporator, superheater and water preheater . The different components are put together to meet the operating requirements of the unit.Modular HRSGs can be categorized by a number of ways such as direction of exhaust gases flow or number of pressure levels. Based on the flow of exhaust gases, HRSGs are categorized into vertical and horizontal types. In horizontal type HRSGs, exhaust gas flows horizontally over vertical tubes whereas in vertical type HRSGs, exhaust gas flow vertically over horizontal tubes. Based on pressure levels, HRSGs can be categorized into single pressure and multi pressure. Single pressure HRSGs have only one steam drum and steam is generated at single pressure level whereas multi pressure HRSGs employ two (double pressure) or three (triple pressure) steam drums.

Technical Features

1. Modular structure, optimize the design, layout reasonable, energy efficient.

2. Spiral fin tubes to improve heat transfer efficiency.

3. All pipes and headers with hydrophobic Hassle elbow, easy and thorough for drain off water.

4. Using suspension structure and insulation within the outer shield in the form of thermal expansion freedom, heat a small.

5. Optimizing select each heating surface pressure drop within the working fluid, the working fluid velocity distribution, safe and reliable water circulation.
