  • What is the relationship between the furnace size and low nitrogen combustion of gas-fired boiler? 2021-11-12
    Boiler furnace is a three-dimensional space surrounded by furnace walls, which is used for burning fuel. The function of the boiler furnace is to ensure that fuel is burned out as much as possible, and to cool the flue gas temperature at the outlet of the furnace to the temperature allowed by the safe operation of the convection heating surface.
  • What is the thermal efficiency of biomass steam automatic boiler? 2021-11-12
    In recent years, the state has stepped up efforts of prohibiting the traditional coal-fired boilers. Major enterprises keep up with the times and purchase various environmental protection boilers. Gas-fired boiler is currently the most popular environmental protection boiler. However, due to geographical limitations in some areas, natural gas is difficult to obtain, or the cost is too high, some enterprises will choose biomass steam boilers.
  • What are the causes and treatment methods of ash leakage in the expansion joint of boiler flue outlet? 2021-11-12
    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.
  • How to design the explosion door for boilers? 2021-11-05
    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.
  • What is a biogas boiler? 2021-11-05
    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.
  • What is the working principle of fully premixed low nitrogen condensing boiler? 2021-11-05
    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.
  • What are the reasons for the rising temperature of boiler exhaust gas? 2021-10-29
    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.
  • What is the relationship between water quantity and steam quantity of gas-fired boiler? 2021-10-29
    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.
