Hot Water Boiler Stack Economizer / Economiser Tubes Anti - Corrosion
(1) HDB consistently executes successful boiler economizer installations using safe, cost-effective methods. Economizers improve boiler performance by increasing fuel efficiency and improving steam generation and response time.
(2) We can guide you through the process of installing or retrofitting existing boiler systems .
Our expert boiler economizer and waste heat recovery system installations can reduce your overall fuel requirements, lower emissions, and ultimately reduce your boiler operating costs.
• Superheating raises overall efficiency as well as avoids too much condensation in last stages of turbine which avoids blade erosion.
• The heat of combustion gases from furnace is utilised for removal of moisture from steam and to superheat the steam.
• Super-heaters ususlly have several tube circuits in parallel with one or more return bends,connected between headers.
• Heat from the hot gases to the vapour in the surperheater is transferred at high temperatures.
• Therefore promary section of superheater is arranged in counterflow and secondary section in parallel flow to reduce the temp.stressing of the tube wall.
|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|
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.|
use for heating saturated steam, steam temperature could be up to 900 degree C.
