When the steam boiler produces saturated steam, due to some reasons of the steam boiler itself, the steam contains water, resulting in insufficient dryness of the steam and water in the saturated steam. In this paper, Jiangsu Sifang boiler briefly analyzes the main reasons.The main reasons are as fo
The economizer of the boiler is generally arranged in the tail flue, and the flue gas temperature is low. When the industrial boiler is started or operated under low working conditions, it is easy to cause the flue gas temperature to be low, thus causing low-temperature corrosion of the tail heating
Regarding this issue, Jiangsu Sifang boiler believes that:1、 Condensate Precipitation Law:Each steam curing cycle of the autoclave goes through three stages of pressure (temperature), constant pressure (temperature) and pressure reduction (temperature). About 80% of the saturated steam in each steam
In view of this problem, Jiangsu Sifang boiler suggests:1. Vacuumize the kettle to reduce the oxygen content in the steamTry to shorten the time of entering and leaving the material truck; The vacuum shall be evacuated and the vacuum degree shall be properly increased before the steam is introduced.
In view of this problem, Jiangsu Sifang boiler suggests:During welding, the gas in the molten pool fails to escape during solidification and remains in the weld, which is called pore.Causes: ① the welding material has not been baked or the baking does not meet the requirements, the welding wire is n
In view of this problem, Jiangsu Sifang boiler suggests:1) When the distance from the site to the control room is long and the resistance of the connecting wire is large, if the voltage source signal is used for remote transmission, a large error will occur due to the voltage division between the wi
The thermal efficiency of the boiler can be calculated by the positive and negative balance methods respectively.1. Positive balance methodThe method of calculating the thermal efficiency by the ratio of the heat used by the boiler to the total heat released by the fuel is called the positive balanc
If the furnace pressure is too low, the air leakage in the furnace and the flue will be intensified, the combustion will deteriorate, the combustion loss will increase, and even the combustion will be unstable until the fire is extinguished; If the furnace pressure is too high, the flame and high-te
The waste heat boiler has a variety of types according to different flue gas compositions, but the same is that the flue gas composition is complex, and the flue gas contains a large amount of dust and cohesive ash in molten state. These ashes will be re bonded on the heating surface of the boiler w
The water and steam system of the boiler and its thermal cycle equipment includes a series of equipment pipes and their evaporation heating surfaces flowing from the raw water into the boiler, and the steam system of the superheated heating surfaces and their steam consuming equipment flowing from t
① Thermal typeThermal NOx is mainly generated during combustion. Nitrogen in combustion supporting air is oxidized under high-temperature flame. It is mainly generated in the area with temperature higher than 1800K. Temperature, excess air coefficient and residence time in high-temperature zone will
A) phenomenon of economizer damage accident (1) the water level of the drum drops abnormally, the water supply volume increases significantly, and is larger than the steam volume, and the water pressure at the economizer inlet decreases; (2) The exhaust gas temperature decreases and the water temper
