Boiler gas combined 4 ton boilers manufacturers service life estimates are have their own life, but some of the old boiler their adjustment has exceeded his useful life, and people can just look back to continue with use, thus increasing the safety of the boiler risks could cause unexpected consequences, so there have been gas-fired boiler, its long service life compared to the old. First: What is the useful life of its own life, longer service life if the boiler, pressure components severe corrosion, dirt knot, overheating, etc. are security risks will increase. The gas boiler a good solution to the above problem, the furnace burning natural gas will not cause dirt, temperature can be adjusted without causing overheating so greatly improve the life of the boiler through the display. Second: the design takes into account the natural gas combustion flame height and diameter in the design, the furnace space is well set and gas, the flame does not scour the furnace surface to reduce damage to the furnace surface to improve efficiency while also protecting the furnace wall, this design is very good. Because the gas-fired boiler design good way to improve the life of the boiler itself, both economic and affordable, but also a good supply, to achieve a good role boiler.

Hot water combined 4 ton boilers manufacturers in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).
After the system control principle of vertical gas-fired steam combined 4 ton boilers manufacturers is turned on the power switch, click the pump control switch to turn on the position, carry on the boiler feed water to rise to the normal position, click the burner power switch, click the start button. The power supply of the control system is turned on and the burner enters the working state. According to the operation procedure of the program controller, the low-fire combustion is carried out first and then into the fire-burning state, and the boiler enters the normal operation stage. When the water level rises to the high water level, the output high water level alarm signal light is lit, accompanied by the sound of the electric bell, and the protection shutdown is realized to cut off the power supply of the controller. When the water level rises to + 30mm, the pump stops running, and when the water level drops to-30mmm, the pump automatically restarts, When the water level drops to ±50mm, the output is extremely high, the warning signal light is lit at the very low water level, accompanied by the sound of the electric bell, and the power supply of the controller is cut off by protecting the shutdown of the furnace. When the pressure rises to 0.72MPa, the overpressure signal, the sound of the electric bell, alarm and cut off the power supply of the control system to realize the emergency shutdown of the furnace. When the pressure exceeds the upper limit of the regulating pressure, the controller outputs a small fire signal to close the fire valve and open the small fire valve to burn in a small fire. When the pressure falls below the lower limit of the regulating pressure, the controller outputs a fire signal to open the fire valve to burn the fire. When the burner failure occurs, the combustion controller automatically closes the valve to stop combustion. When the exhaust temperature is higher than 250 ℃, there is a blue light, accompanied by the sound of the electric bell, and the protection shut down the power supply of the controller.Free Chat
