  • What are the characteristics of gas-fired boilers? 2020-04-24
    1. The control system is equipped with a special computer controller, which makes the boiler running clear and easy to operate. 2. The burner is controlled by full-automatic program, and in case of failure, the burner stops automatically. 3. The boiler body is designed with reasonable structure, and the top is equipped with air vent. The boiler works under normal pressure and is far away from explosion danger. The full wet back three-way structure and corrugated tank design are adopted. The flue gas process is long, the temperature of exhaust gas is reduced, the heat transfer coefficient is increased, and the equipment life is prevented from being reduced due to the expansion and contraction of metal.
  • What is the working principle of the oil-gas separator of a thermal oil heater? 2020-04-17
    Generally, there is moisture in heat medium oil. And, the moisture will be evaporated during the heating process of the oil. If the water vapor is not discharged from the thermal oil heater, it will cause the fluctuation of heat medium oil pressure. However, the oil-gas separator can separate the water vapor from the heat medium oil and discharge it from the heater, which ensures the stable oil pressure.
  • What are the maintenance contents of main systems of a gas-fired boiler? 2020-03-06
    Maintenance of the burner: thoroughly clean the rotor plate, ignition device, filter, oil pump, motor and impeller system, and add lubricant to the connecting rod device of air valve. Retest the combustion condition.
  • 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 material used in the impulse bag filter of biomass-fired boiler? 2020-02-13
    The temperature of flue gas generated by a biomass-fired boiler is relatively high. But it is not corrosive. So, it is suitable to use heat resisting glass fiber needled felt bag which has a good use effect. Moreover, this kind of cloth bag is not very expensive.
  • What is the function of the economizer? 2020-02-07
    The economizer is a heat exchanger equipment which utilizes heat recovery of flue gases to heat feedwater. It can increase boiler efficiency, reduce the temperature of flue gas and save the fuel by absorbing recovery of flue gases. Besides, the feedwater is heated through the economizer before it is supplied into steam drum to decrease the thermal stress of the steam drum wall caused by temperature difference, which can improve the operating conditions of steam drum and prolong the service life of the steam drum.
  • Why do you use low heat generation instead of high heat when calculating boiler thermal efficiency? 2019-12-13
    This is because, under normal circumstances, the exhaust temperature of the boiler cannot completely condense the water in the flue gas, and the difference between the low calorific value and the high calorific value is mainly in the part of the latent heat of vaporization, so the low heat is used. The value is calculated to reflect the true efficiency of the boiler. However, there will be some special circumstances. For example, if the boiler is a condensing boiler, the calculation of the condensed water portion should be calculated using the high calorific value.
