1. Efficient ω Encircling flue gas heat exchange process
The structure has extremely high heat exchange efficiency between flue gas and water pipe. The inner ring hot water exchange pipe and the outer ring hot water exchange pipe form a natural circulation process, which can effectively reduce the salt content of the boiler and reduce the scaling rate;
2. Equipped with integrated condensing heat exchanger
The natural gas boiler is equipped with high-temperature economizer and low-temperature condenser. The exhaust gas temperature is as low as 66 ℃. After natural gas combustion, steam condensation releases a large amount of high-level latent heat value, fully absorbs the high-level heating value of natural gas, and the thermal efficiency reaches more than 100%;
3. Certificate free and fast steam delivery
The water volume of the inner tank is 48.2l, less than 50L, no certificate is required, the steam can be produced in 5 minutes, and the rated steam pressure can be reached in 10 minutes, so the steam can be used quickly and conveniently;
4. Automatic dosing device, guaranteed thermal efficiency
The unique arrangement of water pipes is designed to cooperate with the water supply agent, automatically add the agent to maintain the feed water pH stable at 11-22, achieve the effect of oxygen removal and scale inhibition, reduce the amount of scale, and ensure the thermal efficiency of the boiler for a long time;
5. Full automatic scale monitoring alarm (AMG)
The scaling of the pipe wall is measured by monitoring the exhaust gas temperature of the body. When the scaling inside the boiler is slight, it will automatically alarm, and when the scaling is serious, it will be forced to shut down;
6. PLC control cabinet and high-end imported accessories (AMG)
7-inch color touch screen PLC control, Italy Baide burner, France Schneider Electric Appliance, southern stainless steel vertical multistage pump;
7. Online remote monitoring system (AMG)
Real time monitoring of boiler operation pressure, exhaust gas temperature, body temperature, natural gas supply pressure, burner operation status (including air pressure and ignition device), water level status, boiler fault information, water pump operation status, etc.
