Gas fired boiler flue gas recirculation FGR low nitrogen combustion technology, the high temperature of about 10%~30% of the flue gas at the boiler outlet (the temperature is about 170℃), through the smoke duct into the inlet of the combustion machine, premixed combustion air into the furnace. Gas boilers for sale at reasonable prices, rich production experience, high degree of automation. So as to reduce the temperature of the combustion area, at the same time reduce the concentration of oxygen in the combustion area, and eventually reduce the amount of thermal NOx generation, to achieve the tail of the boiler flue gas nitrogen oxide emissions less than 30mg/m3.
This series of boilers adopt a new design, reduce the emission of harmful substances when fuel combustion. In order to meet the requirements of environmental protection standards, reduce the emissions of nitrogen oxides, meet the low nitrogen emission standards. Applicable to corrugated equipment, cement maintenance, bridge maintenance, food drying and so on. Its wave furnace and back combustion chamber for a return, two, three return for threaded pipe, the upper part of the boiler is arranged with energy saving device. The boiler is equipped with perfect automatic control device and safety protection device with high and low water level alarm and low water level chain protection function; Boiler automatic ignition, burner fire automatic regulation and flameout protection to ensure the safe operation of the boiler.
The fuel of the boilers product is light oil or natural gas; The fuel is ejected from the burner, ignited by the electronic ignition rod, and is burned under slightly positive pressure in the furnace. After burning out, the high temperature flue gas enters the second and third return threaded smoke pipe by turning 180° from the backcombustion chamber, and enters the energy saving device by turning 180° from the upper part of the back smoke box. After heat exchange, it is discharged into the atmosphere through the chimney. Gas boilers for sale in 80%-100 working conditions can be stable operation, is a horizontal internal combustion gas quick loading boiler, the use of wet back structure.
WNS type gas boiler in strict accordance with the thermodynamic calculation standard design on the basis of increased convection heating area, reach or exceed the rated output, boiler safe and stable operation of the working condition range should be within 70% ~ 100% load; The exhaust temperature is low and the boiler efficiency is high. Suitable size of burners, open flame, suitable for all kinds of gas burners. The gas-fired boiler has automatic ignition, program control, water level control, overpressure protection, furnace flameout protection and other control and protection functions, easy to operate, safe and reliable.
Gas boilers for sale natural circulation of working medium, flue gas system for forced positive pressure ventilation, simple structure, convenient manufacturing. Boiler basically does not exist the phenomenon of leakage of smoke and air, less heat loss, high thermal efficiency, automatic control.
