  • What are the characteristics of dust collector of coal-fired boiler? 2020-05-29
    The characteristics of dust collector of coal-fired boiler: 1) Separating the particulate matters. The dust collector of coal-fired boiler can effectively separate the big particulate matters with ignition conditions, so as to reduce the obstruction of dust removal system and improve efficiency. 2) Reducing dust. The dust collector of coal-fired boiler can prevent the dust-contained gas from washing the bag to lower the dust concentration of dust-contained gas and extend the service life of filtering bag and pulse magnetic valve. 3) Adopting materials with high quality. The dust collector of coal-fired boiler adopts high-temperature resistant materials that can extend the service life of dust collector. 4) Adopting elastic piston ring. The mouth of filtering bag adopts elastic piston ring to ensure the leakproofness, which is firm and reliable.
  • What is the proper way to clean a steam boiler? 2020-05-29
    There are many opinions on the best way to clean a steam boiler. One of the oldest ways is to dissolve a pound of tri-sodium phosphate (TSP) and a pound of caustic soda (lye) in water and pour it into the boiler. Let it cook for a few hours and then drain the boiler. If you can't buy TSP in your town, try a commercial soap called MEX. It works well and will not damage the rubber gaskets found in some boilers. However, before you clean any boiler, check the manufacturer's instructions for their recommendations. 
  • What parameters are critical to the health of a coal-fired boiler? 2020-05-15
    Few parameters critical to health of the Boiler are (4)Heat rate of the Boiler. This is a composite index of many performance indicators. Most of them will appear below. (5)Unburnt fuel in flue gas and at boiler bottom . (6)Flue gas furnace exit temperature. (7)Boiler tube metal temperatures. (8)Oxygen in flue gas. (9)Imbalances in flue gas temperature over a cross section. (10)Spray water consumption in Super heater and Reheater. (11)Heat radiation from insulation. The above all affects the performance of the boiler.
  • 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 reason that causes flameout of a gas-fired boiler 2020-05-01
    1.Flamelifting caused by a sudden increase of gas pressure; 2.Gas supply disruptions caused by malfunction of solenoid valve; 3.Great gas constituent change and excessive moisture content.
  • 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 proximate analysis of coal? 2020-04-10
    The proximate analysis of coal is to dry, heat and burn coal samples as required to get the percentage of moisture, volatiles, fixed carbon and ash in the coal and learn about the characteristics of coal combustion.
  • What is the reason for the failure of the draft fan of the biomass-fired boiler? 2020-04-03
    Four factors are related to the failure of the draft fan of the biomass-fired boiler. The factors are electric, electrical motors, dampers and induced draft fans. Therefore, if the draft fan breaks down, you can check the electric and electrical motor first, then you can check the damper and the induced fan.
