1. No boiler inspection and operation certificate - the water volume of the product is less than 29.5l and the pressure is 1.0 / 1.3 / 1.6Mpa. Within the scope of no boiler inspection specified by the state, this type of boiler does not need to apply for boiler use certificate, annual boiler inspection and personnel operation certificate, which is convenient and simple to use;
2. Multiple interlocking safety protection - Electronic overpressure protection, mechanical safety valve overpressure protection, water shortage protection, leakage protection, overheating protection, burner flameout protection, water level logic error protection, etc;
3. International advanced vertical tubular water tube boiler structure - tubular boiler has no drum, and the boiler body is composed of upper and lower headers and tubes, so it is one of the safest boiler structures among all boilers;
4. Equipped with integrated (energy saving + condensation) condensation heat exchanger - high temperature economizer and low temperature condenser are equipped for flue gas tail discharge. The flue gas temperature is as low as 65 ℃, and the condensation of water vapor generated by natural gas combustion releases a large amount of high latent heat value. After absorbing this part of heat, the boiler feed water enters the boiler, and the thermal efficiency reaches more than 99%; The condensation heat exchanger is made of Nd corrosion-resistant steel, which is durable;
5. Steam generation in 2 minutes - tubular boiler structure has small water capacity and short steaming time. It only takes 2 minutes to produce steam. It can reach the rated steam pressure in 4 minutes, and the use of steam is fast and flexible;
6. Innovative downcomer water pipe layout - added downcomer for water circulation to ensure reasonable water circulation of boiler;
7. Humanized industrial appearance design - beautiful and compact appearance design, small floor area, integrated design, extremely convenient installation, maintenance and operation.
Manufacturing basis
1. The boiler design and manufacture shall be selected in accordance with the provisions of the supervision regulation on safety technology of steam boiler.
2. The heating surface materials and welding rods and wires used in the boiler shall have quality certificates.
