Boiler pressure protection means that once the steam pressure exceeds the rated value, interlock protection is required. This is an important protection warning measure in boiler operation.
The main treatment method is to automatically stop the boiler when the operating pressure of the boiler is too high, and the combustion system will stop working; the operating power can also be changed, single-stage or double-stage combustion; the oil quantity (or gas volume) can also be adjusted to achieve proportional adjustment, thereby According to different steam pressures, adjust the burner working load to ensure the safe operation of the boiler.
FANGKUAI uses a variety of advanced equipment and technology to achieve precise pressure control in all directions.
1. Pressure gauge
Specially customized, safe and reliable, and responsive, direct-reading pressure gauges with normal (green) and overpressure (red) working zone indications, which are aesthetically pleasing and easy to observe.
2. Pressure controller
Its main function is to send signals with high and low pressure to the electrical switch, and the external circuit is automatically controlled or interlocked. Fang quickly chooses imported Danfoss pressure controller to make steam pressure overpressure alarm, and cut off the burner when it reaches the limit.
3. Pressure transmitter
The steam pressure in the boiler is converted into a continuous pressure signal, the touch screen directly displays the current pressure, the steam pressure is automatically adjusted, the boiler is stably operated, and energy saving is achieved (selected from Danfoss, Denmark).
4. Safety valve
The safety valve is the last line of defense in the protection of the boiler. When the boiler pressure exceeds the limit, the steam is released according to the setting pressure of the safety valve.
We, Zhengzhou Fangkuai Boiler Co., Ltd. (Fangkuai), are excited to announce our participation in the Indonesia International Heating Technology Exhibition 2025. We will be showcasing our advanced boiler systems engineered for higher efficiency, lower emissions, and sustainable energy performance. Join us at Booth No. B1-08 from November 5–7, 2025 at the Jakarta Convention Center.
The event brings together EXPO BOILER, EXPO BIOMASS, EXPO PUMPS & VALVES, and EXPO CRANE — creating a comprehensive platform for technology exchange and business collaboration across the industrial heating and energy sectors in Southeast Asia.
At the exhibition, we will present our integrated solutions including biomass boilers, industrial steam systems, and full power plant EPC services. Our products emphasize:
