Horizontal E-type loop three-pass full wet-back structure, flanged butt-welded design:
1). Jet-injected internal combustion E-type three-pass wet-back flue gas structure:Fully Automatic Low-Nitrogen Condensing Gas Boiler, this product's design complies with the relevant provisions of NB/T 10941-2022 "Technical Conditions for Small Boilers and Atmospheric Pressure Hot Water Boilers", TSG 91-2021 "Boiler Energy Conservation and Environmental Protection Technical Code", and TSG 11-2020 "Boiler Safety Technical Code". The boiler's dust emissions meet ultra-low NOx emissions of ≤30mg/m³. It employs an E-type shell structure and a full-wet back structure. Fuel passes through an upper-side mounted burner, causing flue gas to flow from top to bottom. Meanwhile, the water flow in the boiler's heat exchange system moves in an opposite direction from bottom to top. Due to the action of high-speed flames creating回流 and entrainment in the boiler drum, the flue gas undergoes cross-exchange after turning 180° into the boiler body, the flue gas condensation energy saver, and the multi-functional heat exchange area coupled with the water pipes. After turning 180° again into the flue gas condensation energy saver, it effectively absorbs the sensible heat in the flue gas and the latent heat released during condensation, resulting in low exhaust gas temperatures. The exhaust gases are then discharged into the air through the chimney, achieving the goals of energy conservation and environmental protection.

The large furnace pot structure increases the heat transfer area, enhances the rigidity of the furnace pot, and accommodates the free expansion after the furnace pot is heated. The convective tube bundle is焊接 from threaded flue tubes, which significantly enhance heat transfer, increasing the heated area, making the boiler structure compact, and reducing the occupied space. A manway is set at the upper part of the boiler body for easy internal inspection and regular maintenance cleaning. The down draft chamber is assembled in an integrated manner, offering good overall design, aesthetics, and elegance, without any potential for smoke leakage.
The smoke condensation energy saver is assembled from front and rear side panels, left and right side panels, and upper and lower tube plates. The convective tube bundle is焊接 from threaded smoke pipes and is integrated with the boiler main body, resulting in low exhaust gas temperature. It effectively increases thermal efficiency, saves fuel consumption, and reduces nitrogen oxide emissions.
This furnace-type heat exchange system integrates the combustion chamber, flue, and water channel into a single design, offering excellent heat conductivity without dead zones.
