The condensing boiler burns carbon-based fuel with oxygen in order to produce steam and carbon dioxide. The gases that escape this process (through a chimney) as exhaust are called flue gases. The major advantage is that they offer up to a 90% improvement in terms of efficiency when compared to standard gas boilers. Overall, condensing boilers are considered much more efficient in contrast to non-condensing gas boilers, a major consideration for any business running on a budget.
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.
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.
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.
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.
The coal-fired boiler refers to the boiler uses various types of coal as fuel and converts the heat of coal to steam or hot water.
There are generally two calculation methods of the circulating water volume of a coal-fired hot water boiler. One is to calculate the hourly water volume of one square meter and the other is to calculate the design parameter volume of every ton. As for the make-up water volume of this type of boiler, it is usually calculated as 1% to 3% of its total circulating water.
