In the work of transforming a coal-fired boiler into a gas-fired boiler, the principle of changing the original boiler should be reduced without changing the pressure component of the boiler body. The transformation process should focus on the choice of gas burners, the determination of the number of burners, the layout of the burners, the matching design of the furnace layout, and the selection of explosion-proof measures. Step by step, both economic benefits and practicality should be considered.
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.
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.
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.
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.
Fuel freezing point is the temperature at which the fuel loses fluidity. It is an important index that indicates the fuel flows at low temperatures. It often refers to the maximum temperature at which the oil surface remains stationary within 1 minute. The higher the fuel freezing point, the lower the low-temperature fluidity. When the oil temperature is below the freezing point, it cannot be transported in the pipeline.
Biomass-fired boilers need to be shut down for maintenance. Proper maintenance can reduce the damage to the boiler caused by continuous work. Firstly, it is necessary to cut off all power to prevent being struck by lightning. In addition, dust, limescale and carbon deposits should be cleaned up to prevent rust and corrosion of the boiler.
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.
