Energy Saving Steel Heat Exchanger Tubes Economizer In Boiler Spare Parts

Energy Saving Steel Economizer Heat Exchanger Tubes Boiler Spare Parts For Utility/Power Station Plant

Product Introduce

Boiler economizers are heat exchange devices with finned tubes that heat a liquid, sometimes water, up to however sometimes doesn't exceed the boiling purpose of liquid.

We can manufacture types of boiler economizer, bare tube economizer, H finned tube economizer and spiral finned tube economizer and gilled tube economizer.

Energy saving principle

Add a heat recovery process to the cycle.Increase the average heat absorption temperature.Thus increasing cycle efficiency.

In the process of starting the boiler (drum boiler), because the cycle of its steam pipe is not established, that is, the boiler feed water is in a stagnant state, at this time the water in the economizer is in a state of non-flow.With the strengthening of boiler combustion and the increase of flue gas temperature, the water in the economizer is prone to vaporization, making the part of the economizer in an overtemperature state.In order to avoid this situation, connect a pipe from the centralized downpipe of the steam drum to the inlet of the economizer as a recirculation pipe, so that the water in the economizer is in a flowing state to avoid its vaporization.

Main technical advantages of our low temperature economizer

1. The equipment body can be designed into many modules to ensure the long term and stable running;

2. The low temperature economizer manufactured by our company can guarantee the wall temperature is 5-10 ℃ higher than the acid , and flue outlet temperature is 10-15 ℃ higher than the wall surface temperature

3. Wall surface temperature can be adjusted according to the boiler load and fuel changer to avoid corrosion under low temperature

4. Changer the DCS system of the existing boiler to achieve the auto and remote control by

computer .

Specifications

The Accessory

The boiler economizer acts as a waste heat recovery device, ensuring that this heat does not go unused.

Instead, the heat is used to essentially preheat the water, so that less heat is required to bring the water to a temperature high enough to make steam

Features

(1) the economizer is a heat exchanger that USES waste heat from boiler smoke exhaust to heat water supply;

(2) the economizer absorbs waste heat of exhaust smoke, reduces the exhaust temperature and improves the efficiency of the boiler;

(3) due to the water supply entering the drum, the water temperature has been raised through the economizer, and the thermal stress on the wall of the drum caused by temperature difference has been reduced, thus improving the working conditions of the drum and extending the service life of the drum.
