Description

Economizer Module With Soft Water Preheater For Korea Waste Heat Boiler With ASME And KEA

(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.

Function

During boiler operation in typical commercial and industrial applications, approximately 10-20% of the heating value of fuel is expelled with the stack gases to the atmosphere. Stack economizers are designed to recover significant amounts of this stack gas energy loss, thereby vastly improving boiler system efficiency. There are several considerations when selecting an economizer:

1, Gas-side Pressure Drop. Added back-pressure on the boiler stack affects the combustion air fan throughput capability. The economizer and combustion air fan(s) must be sized properly in order to assure a suitable system operation and capacity.

2, Feedwater Temperature. The feedwater to the economizer must be deaerated and the temperature setpoint minimally at 220oF to prevent tube corrosion.

3,Water-side Pressure Drop. Feedwater pumps must be sized to accommodate the economizer pressure drop. Additionally, a continuous modulating feedwater system is required to ensure proper flow rates through the economizer.

Performance advantages

1.Application of flue gas waste heat recovery system for tail flue of power plant boiler

The thermal temperature is low, usually 100℃ or so with not good quality.

(1) This part of the recovery of heat is not equivalent to the method of calculation, but should be equivalent conversion method or heat balance calculation to determine the effective use of heat recovery value (thermodynamics second law).

2. Used in other industrial boilers in the flue gas waste heat recovery device

(1) Under normal circumstances, the economy is in priority in power plant application. This is because in other industrial boiler systems, the available steam resources are limited. For users with not enough steam, the recovery of heat can be considered 100% available resources, the most economical.

(2) flue gas waste heat exchanger advantages
