new hot water boiler
1. The main body is a three-way pyrotechnic tube structure with a full-wet, back-back flow in the shell. The flame is combusted in a large combustion chamber with a slight positive pressure to fully expand and the combustion heat load is low. NOx emissions from hazardous substances are low.
2, waveform furnace and thread tobacco structure, both to improve the strength, but also to meet the needs of various parts of the thermal expansion.
3. The main welds are welded using butt joints and are free from damage detection by X-rays and ultrasonics to ensure that the welding quality meets the national requirements.
4, boiler water capacity, ability to adapt to load. A well-designed pot device ensures that the steam rate is less than 4% and meets the higher steam quality requirements of users.
5. It adopts a new type of heat insulation material, which has light weight, low heat loss, and good heat insulation performance.
6, water level alarm using stainless steel electrode rod, PTFE for insulation material. Inserted from above, it is not easy to hang dirt, reliable performance and long service life.
7, front and rear smoke boxes for hinge connection, can be easily opened, maintenance and convenient and quick.
8. Oxygen content adjustment (optional): The system can successfully detect the oxygen content in the flue gas, and transmit the data to the control system in real time. Through intelligent computer analysis, the proportion of combustion equipment is automatically adjusted to make it real-time. Being in the best working condition, the combustion efficiency is greatly improved, which can greatly reduce the fuel consumption.
