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.
Explosion doors mainly use their own weight or strength. When it is greater than or equal to the total pressure acting on the furnace at normal pressure, the explosion-proof door is closed. When the furnace pressure changes, the total pressure acting on the explosion-proof door exceeds the weight and strength of the explosion-proof door itself, the explosion-proof door will be flushed or broken, and a part of flue gas in the furnace will be released, thus achieving the purpose of pressure relief.
The main purpose of boiler acid washing is to remove iron oxide, copper scale, iron scale and other impurities in the evaporation heating surface of the boiler, and also to eliminate silicon dioxide and scale.
Biogas boiler is a kind of boiler using biogas as fuel. It is suitable for new energy boilers in slaughter plants and breeding plants. Biogas boiler is a new type of energy-saving and environment-friendly boiler, which can not only save fuel cost, but also solve the environmental pollution problem.
Fully premixed low nitrogen condensing boiler refers to a boiler using fully premixed combustion technology. Fully premixed combustion refers to a combustion mode in which natural gas is fully mixed with air according to a certain proportion before combustion and air is no longer needed to be supplied during combustion.
The difference between ordinary gas-fired boiler and fully premixed low-nitrogen condensing boiler lies in whether air and natural gas are mixed before or after entering the burner.
Coking and dust accumulation on heating surface. Whether it is slagging and ash deposition on the water wall of the furnace or ash deposition on the superheater, convection tube bundle, economizer and preheater, the measured thermal resistance of flue gas will increase, and the deterioration of heat transfer will worsen the cooling effect of flue gas, resulting in an increase in the temperature of boiler waste gas.
Boiler safety accessories are indispensable parts of boiler operation, mainly refer to accessories such as pressure gauge, water level gauge, safety valve, steam-water valve, sewage valve, etc. These accessories are extremely important to the safe operation of boilers, especially pressure gauges, water level gauges and safety valves, which are the basic accessories for ensuring the safe operation of boilers. Therefore, they are often referred to as three safety accessories of industrial boilers.
First of all, the boiler water and steam are two concepts. It is the unit of measurement for boiling water boiler. What is a boiled water boiler? It belongs to the category of normal pressure hot water boiler, which heats the water temperature to boiling state. To ensure safety in use, the top of the boiler is provided with a nozzle communicated with the atmosphere. If steam is discharged automatically, the boiler will always work under normal pressure, so its attribute is normal pressure hot water boiler.
