  • What is the inlet pressure of a gas burner? 2020-05-01
    The inlet gas pressure is different for different capacity boiler, for example, the pressure for 2 ton steam capacity boiler is about 8~10KPa, while for 4 ton steam capacity boiler is about 12~25KPa. You can tell us the boiler capacity you want, we will help you to get the gas inlet pressure. 
  • What is the oil ignition point of industrial boilers? 2020-04-03
    When the oil temperature rises to a certain temperature that the oil and gas molecules on the surface of the oil tend to saturate, can catch fire and maintain continuous combustion for a duration of not less than 5S. The temperature is called ignition point.
  • How to select a burner for the gas-fired thermal oil heater? 2020-03-20
    The selection of a burner of the gas-fired thermal oil heater should be determined according to the boiler proper structure and fuel characteristics and in combination with the actual conditions and requirements. In addition, this kind of boiler can adopt a waste heat recovery device to improve thermal efficiency and reduce heat energy loss.
  • What are the main factors related to the gas consumption of a gas-fired boiler? 2020-03-06
    Compared with the price of a traditional coal-fired boiler, the operation cost of a gas-fired boiler is relatively high. So, users need to consider the price and quality before purchasing a boiler. For a gas-fired boiler, the energy-saving performance is more important than the boiler price. One year is enough for a gas-fired boiler with good energy-saving performance to save the extra costs of the boiler proper. And, the gas consumption is an important indicator to measure the energy-saving performance of a boiler.
  • What reasons cause the increase of burner noise of a gas-fired boiler? 2020-02-21
    1. If the stop valve of the oil circuit is closed or the feeding of oil is insufficient and the oil filter is blocked, it is necessary to check that the valve in the oil circuit is open, the oil filter works normally and clean the filter screen of the pump. 2. If the oil temperature is low, viscosity is too high or the temperature of the oil fed by pump is too high, the oil temperature needs to be increased or decreased. 3. If the the domestic sewage treatment equipment oil pump breaks down, the oil pump is required to be replaced. 4. If the bearing of fan motor is damaged, it is necessary to replace the motor or bearing. 5. If the fan impeller is too dirty, it is required to be cleaned.
  • What is the standard gas consumption of 10 tph gas-fired steam boiler? 2020-02-21
    The gas consumption of 10 tph gas-fired boiler is related to technical parameters. Such as heating surface layout, heat preservation effect, heat loss, water capacity, etc. The calculation formula of gas consumption of 10 tph gas-fired boiler is as follows: =10 tph gas-fired boiler output÷ thermal efficiency ÷calorific value of natural gas = 6,000,000 kcal ÷ 0.98 ÷ 8,600 kcal / h = 712 m3 Therefore, the gas consumption of 10 tph gas-fired boiler is 712 m3/ h The gas consumption of the above gas-fired boiler is calculated at full capacity. In practice, the gas consumption changes with the operation load and operation conditions. In addition, if thermal efficiency of the gas-fired boiler is different, the gas consumption is different, too. The higher thermal efficiency is, the lower gas consumption is.
  • What is the characteristic of the electric dust collector? 2020-02-13
    Advantages: the efficiency of electric dust collector can reach up to about 99%; large gas handling capacity; low flue gas flow rate, low resistance and low operation costs. Shortcomings: complex structure; large size, large area covering; high investments; complex maintenance; special requirements for dust resistance.
  • What impact will flue gas passes have on boiler performance? 2020-01-10
    The number of passes that the flue gas travels before exiting the boiler has been a good criterion when comparing boilers. As the flue gas travels through the boiler it cools, and therefore changes volume. Multiple pass boilers increase efficiency because the passes are designed to maximize flue gas velocities as the flue gas cools. ZOZEN has developed new design technologies in our WNS series boilers allowing for comparable efficiencies in fewer passes, resulting in smaller boiler systems that will fit in tighter quarters.
