mercial gas steam boiler

WNS type gas mercial steam boiler system control principle: ①, after WNS type gas steam boiler on the power switch, click on the pump control switch open position, after boiler feed water rises to the normal position, click-burner power switch, clicking the start button, the control system power is on, the burner into the working state, according to the operation program for the controller, to be re-ignition burner fires into the combustion state, the boiler enters normal operation this stage. ②, high output level when the water level rose to a high level alarm signal indicator light, when the water level rises to the pump stops running + 25mm, the water pump when the water level falls -25mmm automatic restart, when the water level falls -50mm, outputs a low level alarm indicator light, with bell sound, and cut off the power to the controller to achieve protection shutdown, -75 mm when the water level falls, the output signal of low water level indicator light. ③, when the pressure is raised 0.73MPa, the output signal of the first indicator light overpressure, combustion conditions and off the controller circuit, the controller stops the shutdown. Output when the pressure rises above a second overpressure 0.75MPa signal issued bell sound, alarm and cut off the power supply control system implemented emergency stop. Regulating the pressure when the pressure exceeds the upper limit, the controller output signal of a small fire fire closed valve, a valve to open the small kerosene ignition burner. When the lower limit pressure drops below the regulated pressure, the controller outputs the fire signal to open fuel valve fire, the fire to burn. ④, after the failure of the burner failure occurs, the burner control valve is automatically shut down to stop the oil combustion.

Fuel mercial steam boiler can be converted into a gas steam boilers do? Hello gas can be changed if it is horizontal (1t-4t) of fuel to be steam boiler biomass gasification boiler (transformation without changing the original structure of the boiler pressure), by applying a biomass gasification burner using pyrolysis pyrolysis and chemical oxidation, and sealed by hypoxia smolder, thermal decomposition of the biomass waste to make it work as hydrogen, carbon monoxide, methane and hydrocarbons, is a high-energy combustors for boilers or other use, saving 30-60% of fuel costs while eliminating the chimney smoke, but also greatly reduce the production of sulfur dioxide at the same time to achieve energy saving win.

Fangkuai boiler for you to sort out 30 boiler operation common problems and solutions, after learning, do not forget to share with your friends oh. (6) what are the main factors affecting the wear rate? 1 flue gas, 2 flow rate of the material, 2 particle size of the material in the flue gas, and 3 the surface shape of the worn component. The velocity of air flow is the most important factor affecting the relative direction of motion of the worn material and the wear is proportional to the third power of the velocity. 7. Why should the bed temperature be controlled between 850 and 950? 1 the ash will not melt at this temperature, thus reducing the risk of slagging 2. Higher desulfurization efficiency 3 less nitride gas in combustion gas at this temperature 4 Alkali metal in coal does not sublimate at this temperature, which can reduce slagging on the heating surface. 8, why do you have to blow the boiler pipe? Some equipment in boiler steam-water system, such as dewarming water, start-up bypass, superheater, reheater pipeline system, are not suitable for chemical cleaning due to structure, material, arrangement and other reasons. So it is necessary to use the physical method to remove the residual debris before the new boiler is put into operation, so the steam produced by this furnace is used to blow the steam-water system and equipment. 9, what are the common methods of boiler maintenance? (1) Wet protection: there are diammonium method, ammonia method, maintain feed water pressure method, steam heating method, alkali liquefaction method, trisodium phosphate and nitrous acid mixed solution protection method; (2) dry protection: there are drying method (with pressure discharge) and desiccant method. 10, which causes the deterioration of steam quality (steam pollution)? (1) steam with water. The boiler's feedwater contains impurities. The feed water is heated into steam after entering the boiler, and most impurities are transferred into the boiler water. So many cycles, the impurity concentration in the boiler water becomes higher and higher. Furnace water containing high concentrations of impurities is carried by saturated steam, which is called steam carrying water, which is called mechanical carrying. The first reason for steam pollution. (2) Steam-soluble salt. At higher working pressure, steam can dissolve some salts, which is called selective transport, which is the second reason of steam pollution.
