1.WNS type gas pressure hot water boiler is a horizontal quick-loading internal combustion three-return fire tube boiler. The wet-back structure of the biased furnace is adopted, and the high-temperature flue gas successively washes the second and third return flue pipes, and then exhausts into the atmosphere through the meat from the back flue chamber.
2. The application of enhanced heat transfer elements such as corrugated furnace bile and threaded smoke pipe not only enhances the heat transfer effect, but also effectively absorbs the thermal expansion and contraction of the furnace body.
3. Stainless steel packaging, corrosion resistance increased;
4. Leakage protection function: the control system will automatically cut off the power supply after detecting leakage of the electric heating element;
5. Gap water protection: when the boiler is short of water, the burner control circuit is cut off in time to prevent the burner from dry burning damage, and the controller issues a water shortage alarm indication;
6. Port pressure protection: equipped with explosion-proof doors, automatic rebound after port pressure, to ensure the safety of steel furnace;
7. Real-time water level monitoring function: equipped with electronic water level detection device, real-time control of boiler water level;
8. Time setting function: Users can freely set the start and stop time of the boiler according to their needs.

Biomass pellet fuel is a major research achievement in the application of fuel, it is the use of straw, rice stalk, adhesive wood, wood chips, peanut shell, melon seed shell, beet pulp, bark and other all degrees of abandoned agricultural crops, by grinding, mixing, extrusion, drying and other processes, and finally made into granular fuel. Its raw materials are widely distributed, the processing technology is advanced, and the biomass fuel is known as green coal, which is a clean energy. As the fuel of the boiler, it has a long combustion time, a high temperature of the intensified combustion furnace, and is economical, while there is no pollution to the environment, it can replace wood, coal, natural gas, and is an energy-efficient environmental protection product.
