The following conditions will occur when a gas-fired boiler is leaking:
The working pressure of natural gas changes.
There is a strong airflow sound near the source of the leak.
The hand-held alarm makes an abnormal sound.
If the boiler has a serious leakage, the fixed alarm will issue an automatic alarm and the exhaust fan will be opened automatically.
First of all, we should consider the thermal insulation effect. The main function of a gas-fired boiler is to provide heat energy. Good surface packaging material can avoid heat loss and save the fuel. It is suggested to choose glass wool which has a good insulation effect.
Secondly, we should consider the boiler appearance. It is best to choose a white color plate package when buying a gas-fired boiler, which not only has a beautiful appearance but also has a good insulation effect.
Finally, we should consider the boiler size. Wrong boiler size will cause some unnecessary troubles.
If the following three conditions occur during the burning and flame out process of a gas-fired boiler, the furnace is likely to blow up.
1.The residual gas content in the furnace reaches the ignition limit at the start-up phase of the furnace.
2.The fuel content in the furnace reaches the ignition limit after several times failure of ignition.
3.The fuel is sprayed out because of the halfway extinction of the flame. And, the temperature of the furnace can not meet the spontaneous combustion condition of the sprayed fuel. However, the content of the sprayed fuel reaches the ignition limit.
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.
Biomass fuel can be applied to a biomass-fired boiler by treatment and compression molding. Commonly used are straw particles, rice husk particles, wood particles, sawdust particles, peanut rod particles, sugar aldehyde residue particles, palm shell particles and so on.
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.
