3. The horizontal gas boiler has a three-pass full wet back structure, and adopts a large furnace and thick smoke tube design to increase the radiation heat absorption of the furnace and effectively save energy and reduce consumption. The use of threaded smoke pipes and corrugated furnaces greatly enhances the heat transfer effect and greatly saves fuel consumption.
4. The boiler is designed according to the normal pressure structure, and the boiler is in a pressureless state, and there is no safety hazard. It adopts high-grade centrifugal glass wool multi-layer insulation, and famous white color steel plate as outer packaging, which has less heat loss, beautiful appearance and rust resistance.
