Economizer
Increase the heat exchange area of the boiler economizer. For example, adopting the economizer whose actual internal area is 1-2 times larger than the ordinary can effectively reduce the flow rate of flue gas, improve the heat exchange efficiency and lower the exhaust gas temperature.
Air preheater
An air preheater is installed with the connected pipe behind the economizer, which can effectively increase the air temperature for supporting the combustion, improve the fuel ignition ...
The boiler water level gauge is a detection instrument that shows the water level of the boiler, and it is one of the important safety accessories of the steam boiler.
Drum boiler refers to boiler equipment with boiler drum, which is an important pressure component in natural circulation boiler and the connecting hub of the three processes of boiler heating, vaporization and overheating, and plays a connecting role. Water becomes qualified superheated steam in the boiler, which goes through three processes: heating, vaporization and overheating. Heating from feed water to saturated water is a heating process; The vaporization of saturated water into saturated steam is a vaporization process; Heating saturated steam into superheated steam is an overheating process.
During the operation of automatic boiler water softener, the role of salt is to backwash sodium ion resin to prevent the sodium ion resin from being poisoned by iron, so the salt will not be destroyed during operation. Pay close attention to the salt content in the salt tank. As long as the salt is continuous, there is no requirement for the salt content. However, for good control, the amount of salt is generally about two-thirds of the salt tank, and then filled with water.
Recently, some users have come to consult how to solve the ash leakage at the expansion joint of boiler flue outlet. ZOZEN Boiler suggested that in case of ash leakage from the expansion joint at the boiler flue outlet, please contact the professional industrial boiler manufacturer.
First, let's explain what an industrial oil-fired boiler is. The industrial oil-fired boilers refer to boilers that use oil as the fuel. Generally, they burn diesel oil, special fuel oil for boilers, heavy oil and waste oil, etc. However, due to the rising price of diesel oil and the problem of supply, they are now turning to fuel oil.
Heavy oil for industrial boilers, namely fuel oil, is mainly made from petroleum cracking residue and straight-run residue, which is characterized by high viscosity and contains many non-hydrocarbon compounds, gums and asphaltenes. Among them, the viscosity of industrial boiler special oil is an important performance index of fuel oil, and it is also the main basis for dividing fuel oil grades.
Low-pressure boilers operate at a lower pressure and reach lower temperatures than high-pressure steam boilers. Water in low-pressure boilers is not heated beyond 250ºF, and the steam pressure does not exceed 15 psi (pounds per square inch).
