1. During the start-up process of the burner, if the burner repeatedly alarms and locks, it should be found out the reason, find the fault and eliminate it, and then press the reset button to inherit the start. Note: The continuous press of the reset button should not exceed 10 seconds
2. If the burner is not successful in one combustion, the natural gas boiler induced draft fan should be restarted, and the second combustion can be started after 5 minutes of ventilation.
3. In the normal operation era, the burner close to the thermal equipment department (such as the connecting flange, etc.) will be very hot, to prevent the formation of burns. Do not place flammable materials in the vicinity to avoid causing fire.
4. During the operation of natural gas-fired boilers, it is necessary to closely supervise the working conditions of hot water circulation pumps and natural gas-fired boiler pressures, natural gas distribution bags, pipeline valves, pressure gauges, flow meters, and water
Missing insulation reduces the system’s efficiency. Insulation helps hold heat in the system, and when the heat can dissipate, more fuel is needed to maintain proper temperature and pressure.
Since missing insulation may not be visible, the best way to detect it is with a thermal imager. If you don’t have a thermal imager as a part of your building’s operations, a plumber or other professional likely will carry one. If your energy costs have increased without a rise in the amount you use the boiler, suspect missing insulation and call to have the system inspected with a thermal imager.
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.
The thermal oil heater is a heater that uses heat medium oil as medium for heat transfer. The low-pressure and high-temperature heating can be realized by the utilization of the high-temperature characteristics of heat medium oil.If there is too much moisture in the low-temperature heat medium oil, there will be pressure fluctuations, which will cause some other problems. In addition, if the heat medium oil does not flow in the furnace owing to the stop of pump, the oil temperature will rise and exceed the limit value, which not will greatly affect the service life of the heater and cause the deterioration of the heat medium oil.
If the circulating pump of a thermal oil heater stops working suddenly. Then, some measures should be taken immediately to remove the fire source. If not, the stop of circulating pump will cause coking in the oil tube, which will shorten the service life of the heater.
The combustion air preheater is definitely one of heat exchanger applications. Based on Figure 1 below, flue gas simply leaves steam boiler and passes via air preheater. The combustion air is passed through this equipment too to increase its temperature before being combined with boiler fuel.
Because the temperature of combustion air is lower than the temperature of flue gas, combustion air receive heat transfer from flue gas through combustion air preheater in the process of convection heat transfer. The heat transfer make temperature of flue gas lower and consequently minimizes its heat loss and also decreases the air temperature to stack.
Efficiency is especially important on a large scale and manufacturing and production operations are no exception. Here are two key reasons why you may want to consider upgrading your industrial heating equipment or installing a new, highly efficient thermal fluid heating system in your plant or facility.
A dryback boiler has a rear wall that is lined with refractory, a wetback boiler has a rear wall that is jacketed by water. Because of this fact, wetback boilers typically boast higher efficiency than dryback boilers as the heat from combustion goes directly into heating water instead of refractory. Wetback boilers are also more forgiving with load changes as the reversal chamber of the boiler is totally submerged in water creating an even heat transfer on the intermediate tube sheet to furnace joint.
