Background
The economizer is a device which is arranged at the lower part of a flue at the tail part of a boiler and used for recovering the waste heat of exhausted smoke, heats the water fed by the boiler into a heating surface of saturated water under the pressure of a steam drum, and is called as the economizer because the economizer absorbs the heat of high-temperature smoke, reduces the exhaust temperature of the smoke, saves energy and improves the efficiency.
There are various ways to classify economizers, and they can be classified as follows. According to the degree to which the water is heated: it can be classified into non-boiling type and boiling type. The method comprises the following steps of: there are cast iron and steel tube coal economizer. The non-boiling type coal economizer is mostly made of cast iron, but is also made of steel pipes, and the boiling type coal economizer is only made of steel pipes. The cast iron economizer is mainly applied to boilers with the pressure less than or equal to 2.5 MPa. If the pressure exceeds 2.5MPa, the coal economizer made of steel pipes is adopted. The device is divided into: there are vertical and horizontal types. Dividing according to the relative flow direction of the exhaust smoke and the water supply: there are three types, forward flow, reverse flow and mixed. According to the structural form: light pipe economizers and finned economizers. The finned economizer comprises: h-type economizers (used more) and helical fin economizers. According to the heat conduction mode: direct conduction and indirect conduction; the direct conduction is to preheat the water for the boiler by directly radiating the tail gas of the boiler; indirect conduction is the indirect preheating of boiler water through a heat transfer medium.
In spite of various structural modes, the partition wall contact between the boiler tail gas and the heat absorbing medium is involved in various types of economizers. In the contact process, salt and dust in the flue gas are easy to attach to the pipe wall of the economizer, so that the heat exchange effect of the economizer is influenced, energy waste is caused, and even the internal blockage of the economizer can be caused to influence the negative pressure of a hearth in serious conditions. Therefore, how to avoid the attachment of salt and particles in the flue gas on the pipe wall of the economizer becomes a technical problem to be solved urgently.
