Product Description
Spiral type H type fin tubes boiler economizer ASME For circulating fluifized bed boiler
Introduction
| Exhaust heat loss is the largest of the heat loss of the power plant boiler, usually 5% to 8%, accounting for 80% of the total heat loss of the boiler or higher. |
| The main factors that affect the heat loss of the exhaust gas are the boiler exhaust temperature. Under normal circumstances, the exhaust heat temperature increases by 10 ℃ and the exhaust heat loss increases by 0.6% ~ 1.0%. |
| China's current thermal power units in the boiler exhaust gas temperature is generally around 125 ~ 150 ℃, the actual smoke temperature is higher than the design value is ubiquitous phenomenon. |
Low temperature economizer
| "Low temperature economizer", can greatly reduce the flue gas temperature, so that the flue gas temperature be reduced lower 40 ~ 50 ℃ or more. |
| The energy absorbed by the "low temperature economizer" can be used to heat the condensate or to increase the temperature of the combustion air by heating the air through the heater. |
| Power plant boiler using "low temperature economizer", can save 1 ~ 4g / kWh, unit efficiency increased by 0.2 to 1.2%. "Low temperature economizer" in the full recovery and utilization of exhaust heat at the same time, but also to achieve the best desulfurization efficiency of smoke temperature, greatly reducing the desulfurization tower to reduce the smoke and water spray cooling water consumption. |
| Under normal circumstances, it takes 1 ~3 years for power plant 1 to recover the investment in "low temperature economizer" and its system equipment , that is to say, the economic benefits are enormous. |
Function
(1) The economizer is a steam generation system as like a boiler. when the exhaust gas discharge from the engine cylinder through the exhaust valve it goes to the boiler for generate steam by heating of water.
(2) After those gas it goes through the economizer the remaining exhaust gas temperature is heated the water in economiser. it help to generate steam, and it is improving the efficiency and save the fuel consumption
(3) An economizer uses the waste heat from the boiler exhaust, that would otherwise be lost to atmosphere to (in most cases) preheat the feed water into the boiler.This improves the boiler efficiency and reduces fuel costs.
*Note:HD BOILER can bespoke special type of economizer according to customer's requirement.

Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification
Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification Introduction The H-shaped finned tube is also known as the H-shaped fin tube, also known as the butterfly fin tube. It is to weld symmetrically two pieces of steel with an arc in the middle to form fins (ribs or butterflies), the frontal shape of which resembles the letter "H", so it is called the H-shaped finned tube. The two fins of the H-shaped fin tube are rectangular and approximately
