Gas-fired hot water boiler has high-tech automatic control system, equipped with a number of protection devices, water shortage protection, overpressure protection, flameout protection, abnormal pressure protection, flue overtemperature protection. The structure of industrial hot water boilers adopts high and new technology, which has small body protection, compact structure and convenient installation. The boiler has simple operation, automatic adjustment, pressure fuel to atomization, micro positive pressure combustion to make the fuel combustion more fully, reduce the loss of fuel and gas emissions, modern industrial steam is convenient to use, energy saving, standard products.

The structure of hot water boiler is designed according to atmospheric pressure, and the top is provided with a big air hole. The boiler works under atmospheric pressure and is far away from the danger of explosion. The boiler body adopts computer optimization simulation design, which completely optimizes the size of the boiler and makes the shape harmonious and beautiful. The series gas fired boiler adopts full wet back three return structure, long flue gas flow, reduce the exhaust temperature, full corrugated furnace set, so that the flame has a strong disturbance, heat transfer coefficient, and effectively due to metal thermal expansion and contraction of equipment life reduction; The gap between the large diameter pipe and the large hole bridge makes the scale coating thin and easy to clean in the same time.

Industrial hot water boilers air oil (gas) automatic proportion adjustment, good atomization effect, full combustion. Under normal circumstances, the output of the gas hot water boiler automatically adjusts the length of the combustion flame with the boiler temperature. When the boiler outlet temperature is set, the burner automatically stops burning. When the temperature is lower than the set value, the burner automatically starts to work. When the occurrence of fuel, air intake abnormal phenomenon, the fault light, program control device will immediately stop the output of fuel, the combustion machine automatically shut down.

In addition to sensible heat of flue gas, water vapor also takes away a lot of latent heat of vaporization. If by reducing the exhaust temperature, all or part of the steam in the flue gas is condensed, and the latent heat released by the condensation process is recovered and utilized, the effective utilization heat of the boiler is increased, and the thermal efficiency of the boiler will be significantly improved. Due to the use of large size furnace structure and flue gas recirculation technology, for gas boiler, can completely achieve ultra-low nitrogen emissions, NOX emissions ≤30mg/Nm3.

Industrial hot water boilers in normal circumstances, the output of the combustion machine with boiler pressure and automatic adjustment of combustion. When the outlet pressure reaches the set value, the combustion machine will stop automatically. When the pressure is lower than the set value, the combustion machine will start automatically. When there is a lack of phase, ultra-high pressure, ultra-low water level, ultra-high water level, suction of foreign matter in the air inlet of the combustion machine and other phenomena, the combustion machine will automatically stop, the fault light, the program control device will immediately stop the output of fuel, to restart the furnace after eliminating the fault.
