Industrial and Utility Alloy HRSG Heat Recovery Steam Generator for Industry

Product Descripton

Heat Recovery Steam Generators are a type of Waste Heat Recovery unit which uses waste heat (generally from Gas Turbines) to generate steam. Therefore, HRSGs are generally attached to the exhaust of Gas Turbines. They are commonly used in Combined Cycle Power Plants where both Gas and Steam turbines are used to drive generators. Common parts of a heat recovery steam generator include the following:

1. Superheater and desuperheater
2. Steam drum, mud drum, drum internals
3. Tubes
4. Duct Burner for supplemental firing
5. Blow down tank
6. Economizer
7. Firing equipment including duct burner, burner management system, pilot burner
8. Bypass stack and exhaust stack, sealing air fan,baffles, piping, valves and controls

Parameter

Configuration

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.

Attention

1. The heating surface of this type employs suspension structure which is good for absorbing boiler expansion and makes it safe in operation.
2. The three cast-off mixed burning and blown gas waste heat boiler uses special sealing devices to reduce boiler air leakage and improve boiler efficiency.
3. The heating surfaces employ reasonable flue gas velocity design to prevent soot accumulation.
4. Straight-arrangement adopted keeps the heating surface clean and improve the heat exchange efficiency.
5. This equipment organizes flue gas dynamic field to the flow of flue gas steady and uniform.
6. The convection tube-bank employs assembled structure with fast installation and low cost.

Supervision and confirmation

The quality and technical supervision administration authorizes the inspection agency stationed on site to supervise, inspect and test the process of boiler manufacturing.Accept supervision or confirmation of the third party or Customer's representative over the process of boiler manufacturing.
