Low nitrogen condensing steam boiler adopts horizontal internal combustion full wet back flue gas three return or two return structure. The combustor of condensing horizontal gas boiler uses the corrugated furnace formed by cold spinning to ensure the full combustion of fuel. It is good for absorbing thermal expansion, providing flexibility, reducing thermal stress and prolonging boiler service life. It can disturb the flow of high temperature flue gas, strengthen the heat transfer, increase the heating area and improve the thermal efficiency of the boiler.
The convection heating surface of horizontal gas steam boiler uses threaded flue gas tube, which makes the flue gas from laminar flow to turbulent flow, increases the heat transfer effect, improves the boiler thermal efficiency, saves fuel, and effectively reduces the operation cost. This series of steam boiler has a large steam space, boiler steam separator layout is reasonable, but also to ensure the quality of steam. Explosion-proof door is installed at the outlet of the boiler to prevent explosion caused by high pressure in the furnace, which is more safe and reliable for users to use.
The front and back smoke box cover of low nitrogen gas fired boiler adopts integral movable type, which has good sealing effect and convenient maintenance. The boiler is equipped with condensate and drainage device of the front and rear smoke boxes, which can drain the condensate water in the front and rear smoke boxes at any time to prevent tube plate corrosion and prolong the service life of the boiler. Condensing horizontal gas boiler with high heat resistance fiber cotton and stainless steel cover, beautiful appearance, strong, corrosion resistance. Low surface temperature of boiler furnace, good insulation performance, improve thermal efficiency.
This series of gas-fired boilers are equipped with high-quality automatic water softener and dosing pump, which can automatically complete the whole process of water softening, dosing and resin regeneration. Select international famous brand burner (low NOx burner), high combustion efficiency, automatic proportional adjustment, ensure full combustion, and can reach the rated output, reduce boiler pollution, energy saving and environmental protection. The condensing heat exchanger can be selected at the exhaust outlet, and the water vapor in the condensing flue gas can absorb the condensation latent heat, so as to improve the thermal efficiency of the boiler.
Gas steam boiler can be equipped with unique energy saving device, improve the boiler thermal efficiency, reduce the boiler exhaust temperature, to achieve the purpose of high efficiency and energy saving. Configuration quality intelligent control system, the boiler has the function of manual and automatic, intuitive interface is concise, running status be clear at a glance, set a stop running, high and low water level alarm interlocking protection, overpressure or overtemperature alarm interlocking protection, stall the interlock protection and so on many safety interlock protection function, to ensure the safe operation of the boiler.
Condensing horizontal gas boiler is equipped with leakage protection function, once the control system detects electric heating element, leakage, the boiler will automatically cut off the power supply. In order to ensure the safety of workers and boiler, improve the service life of boiler. The control system of this series gas-fired boiler controls the start and stop of the circulating pump according to the furnace water temperature. When the furnace water temperature reaches the set upper limit, the hot water circulating pump starts; when the temperature is lower than the set lower limit, the hot water circulating pump stops. The tail of the boiler has a condenser. The waste heat discharged from the tail is used to improve the inlet temperature of the boiler and reduce the exhaust temperature, so that the thermal efficiency of the boiler can reach more than 100% and the operating cost can be saved.
