There are many ways to classify boiler economizer design, which can be classified as follows:
1. According to the degree of heating of the feed water: it can be divided into non-boiling type and boiling type.
2, according to the manufacturing materials: there are two kinds of cast iron and steel tube economizer. Non-boiling type economizers are mostly made of cast iron, but they are also made of steel pipes, while boiling type economizers can only be made of steel pipes. Cast iron economizers are mostly used in boilers with a pressure of ≤2.5MPa. If the pressure exceeds 2.5 MPa, an economizer made of steel pipe should be used.
3, according to the form of the device: there are two types of vertical and horizontal.
4. According to the relative flow direction of exhaust and feed water: there are three types: downstream, countercurrent and hybrid.
5. According to the structure: light pipe economizer and fin type economizer. The fin type economizer includes: an H-type economizer (used more) and a spiral fin economizer.
6, according to the form of heat conduction: direct conduction and indirect conduction;
Boiler square cast iron boiler economizer designCharacteristics:
1. Absorb the heat of low-temperature flue gas, reduce the exhaust gas temperature, reduce smoke loss and save fuel.
2. Since the feed water is heated in the economizer before entering the steam drum, the heat absorption of the feed water on the heated surface is reduced, and the economizer can be used to replace the partially evaporated evaporating heating surface.
3. The temperature of the feed water is increased. When entering the steam drum, the wall temperature difference is reduced, the thermal stress is reduced accordingly, and the service life of the steam drum is prolonged.
