1. The design, manufacture and inspection of the products are carried out in strict accordance with the standards and regulations of "Safety Technical Supervision Regulations of Organic Heat Carrier Furnace", "Safety Technical Supervision Regulations of Hot Water Boiler", GB/T17410-2008 "Organic Heat Carrier Furnace", and have been inspected by the national special equipment safety supervision institution, which is safe and reliable. 2. The boiler heating surface is fully welded with gas protection welding, and has been qualified by X-ray flaw detection and hydraulic test to ensure that the welding quality is higher than the national standard.

3. The diameter and length of the radiation coil are fully adapted to the flame of the matching type burner to ensure the reliable operation and full cooling of the coil.

4. On the basis of rigorous calculation of convection heating surface, a higher and reasonable flow rate of flue gas is adopted to ensure sufficient heat transfer of furnace body and high thermal efficiency of boiler system

5. The boiler body adopts reasonable structural design and high quality refractory and thermal insulation materials, so that the outer surface temperature of the furnace body W 50°C is higher than the national standard requirements.

6. The main body of the boiler is assembled from the factory, and the combustion system, piping system and electric control system can be installed after the user is in place on the site. The installation period is relatively short and the cost is low.
