Description

China Manufacturer Steam Superheater and Reheater for Boiler or Furnace Parts waste to energy

Reheater for Boiler or Furnace Introduction

1. Power station furnaces may have a reheater section containing tubes heated by hot flue gases outside the tubes.

2. Exhaust steam from the high-pressure turbine is passed through these heated tubes to collect more energy before driving the intermediate and then low-pressure turbines.

Reheater Function

1. Therefore the number of reheat stages can not be many as the pressure drop will reduce efficiency of thermal cycle.The steam pipes and reheater coils are to be so designed to limit the drop to 2–3%.

2. The control valves in reheat steam path is not desirable.Systems using HP LP bypass require these valves to control steam flow during bypass operation.

3. The efficiency of the Reheat cycle can be improved by increasing the pressure and temperature of steam entering into the turbine. As the initial pressure increases the expansion ratio of the turbine also increases and the steam becomes quite wet at the end of expansion.

Main Advantage

The main advantage of reheat cycle is to reduce the specific consumption and consequently reduce the size of the boiler and other auxilaries for the same power.The reheat cycle is preffered for the high capacity above 100 MW plant.

Differences

Type Advantages Disadvantages Supporting method
Pendant-type 1.Firm structural support 1. Flow blockage by condensed steam 2. Needs slow restart to purge the water that accumulates in the bottom. supported from above
Inverted-type 1.Proper drainage of the condensed steam 1. Lack the structural rigidity, especially in high speed gas flow Supported from below
Horizontal -type

1. Proper drainage

2. Good structural rigidity.

 1. They do not view the flam directly so they are mainly from the convective type Usually supported in the vertical gas ducts parallel to the main furnace.
