The boiler has a fire tube structure. The oil or gas, after splayed from the burner and nebulized, burns under the micro-pressure in the internal furnace. The high temperature flue gas transmits heat along the internal furnace and brushes the heated surface of the flue pipe, comes to the upper flue tank after convective heat exchanging, and emits into the air through the chimney. The boiler is provided with an import burner which is fully automatically controlled by program, has high degree of automation, and realizes optimized burning effect of the boiler. The boiler model is also provided with an import original burner, which is designed by full analog control of computer, has more compact structure and more convenient installation and maintenance, and can realize the fully optimized design of the flow of the heated surface and the flue gas. High grade centrifugal glass wool with multiple layers is adopted for insulation to reduce heat loss, and the imported colorful steel plate packaging has a nice-looking appearance.
Pressure-bearing hot water boiler adopts a downstream triple-pass wet-back structure which is reasonable and compact.
The internal furnace adopts the waveform internal furnace structure, which not only increases the irradiation area and the convective heat transmitting area, but also meets the demand of the automatic inflation of the internal furnace after high-temperature irradiation.
The boiler adopts threaded flue tube which enhances the heat transmitting efficiency and significantly increases the heat efficiency.
The demountable flue tank gate realizes convenient maintenance of the boiler.
The upper part of the pressure-bearing boiler is provided with a gas-collecting device and the water inlet is placed at the top, thus the operation condition of the boiler system is improved.
