Steam boiler automatically displays the instrument will encounter in the use of water which asked 20 ton steam boilers by fuel can be divided into electric steam boiler, steam boiler fuel, gas steam boilers. According to the structure can be divided into vertical steam boilers, horizontal steam boiler, steam boiler small single, double back to the vertical structure, large steam boiler mostly as three-pass horizontal structure. When the water level is low or groundwater automatically display meter, installed in the steam boiler only a low level means, even water too thin; when the groundwater level automatic means or instruments show lower, the steam boiler is mounted in a water only means; e no other ground water drainage means drainage cock; drum means on a level effective means further water damage; plug door apparatus can not twist the water level; a level plug door apparatus leakage leakage; means water false water level display; water level on the two drum devices are inconsistent; water glass breakage frequently means; glass protection device is not level; water means water level glass plate red indicator is not displayed; glass plate It does not show red; red glass panel is not displayed. If the apparatus dirty water, the water level can not be clearly observed. Steam boiler water level gauge inconsistencies mainly glass and clear observation of steam boiler water level gauge is not cleaned for a long time during operation, routine maintenance is not performed, resulting in water means cocks rust, soda connecting tube blockage. Or filler inadequate or aging. In addition to steam, water or tap is blocked, the phenomenon of false water level may also be due to misalignment between the steam pipes and caused the water level instrument; steam, dislocation faucet handle position will result cocks closed, but may also be due to boiler poor water quality, and water vapor and water and the water level caused by false. Broken glass is mainly water vapor, the centerline of the tap out of alignment, the bending stress in the glass tube memory, no glass expansion gap length is too large, the water level window directly blown cold, poor quality glass. During the boiler operation, we found that the water level is unclear, when the ultra-high water level should be stopped immediately, should discover the problem.
Contrast gas 20 ton steam boiler and gas steam boiler? Which is more cost-effective? There are new users will ask gas steam boiler and gas steam boiler which is more cost-effective in a number of economic operation? Believed to be ready to buy a steam boiler of every business relationship or personally, with you today, I will work together to analyze these two boilers in operating costs to do a comparison. First, the first point to analyze procurement costs: Because gas steam boiler in the annex above techniques and configurations to be clear leadership and gas steam boiler, gas steam boiler supporting a dedicated burner, a burner just put the cost price opened, so that the same tonnage of steam boilers, steam boilers high gas prices than gas steam boiler more. The second point to analyze construction costs: The costs mainly from the boiler room, boiler tubes of steam investment funds. In which the gas steam boiler because more appropriate auxiliary equipment, so in the boiler room construction funds to be more. There is a gas steam boiler automatic control operation, and automatic alarm and automatic protection function. Connected to the gas pipeline, the burner will automatically supply costs can effectively save staff. Gas-fired steam boiler because of the need of coal on the program, so in terms of personnel expenses wage will be larger. The third point to analyze the environmental cost: major review means that now more stringent gas steam boiler. The gas steam boiler due to the operation of the economy, environmental protection and energy saving, as well as government policy to encourage more and more widely used. The fourth point to analyze fuel costs: gas steam boiler will be much higher than the steam boilers in gas fuels. After analyzing the above four points of view than the gas steam boiler Gas steam boiler in order to save more on operating costs, but gas steam boiler environmental protection, now increased pollution than gas steam boiler in environmental protection in recent years so the state more stringent control of environmental pollution, so in accordance with the requirements of environmental protection point of view has an advantage gas steam boiler.
Check gas boiler before the preparation of cease-fire and that the flue slow cooling drum; open all manholes and hand holes in the header of the boiler body; let go of the gas within the boiler drum and water; the boiler combustion chamber, drum , flue ducts thorough cleaning; steam pipeline cleaning and removing rust and scale water; repair or replace a manhole cover; ready safelight, flashlights, test rods, tools and the like. Burner gas is an important part of the boiler, the main control system and combustion system components, the problem lies in easy control cabinet, 1. However, the normal ignition off this failure phenomenon typical cause of several tens of seconds after the self-ignition of the burner flame sensor dirty parts. The flame sensor is a photoresistor when irradiated with light of its own resistance decreases resistance value increases as a state of high impedance low impedance state when the light irradiation. Burner flame sensor controller in accordance with a resistance value to determine whether the process is continued if the combustion stop combustion flame sensor high impedance supply is immediately stopped to prevent the unburned diesel fuel reservoir. Flame sensor probe positioned within the burner duct, since the black smoke, tempering, blowing dust and other reasons that the surface thus losing readily soiling the photosensitive functionality. Check sensor probe, its surface is cleaned with a detergent or alcohol, if necessary. 2. Ignition normal exhaust smoke color but not normal diesel fuel injected into the burner is burning the mixture under stirring, when the appropriate amount of blowing water vapor and CO2 exhaust gas atomization are colorless. When there is insufficient air supply can cause incomplete combustion of diesel soot to form CO and thus give rise to the phenomenon of black smoke exhaust. However, if a strong wind inlet excessive combustion of oil mist may be blown off too late will form white smoke is discharged. Common causes of black smoke exhaust of combustion into the throttle opening is too small, white smoke into the throttle opening is reason to see through the large, two cases should be re-adjusted into the throttle. Exhaust smoke color can be observed while the side damper opening degree until near colorless in exhaust smoke color adjustment. Another reason is that black smoke exhaust poor atomization of diesel, oil mist contained in the larger droplets, can not be sufficiently mixed with the air due to a local incomplete combustion produce soot.
In October 2016, my company and the China Dunhuang International Hotel signed a ZWNSL2.1-1.0 / W-Y.Q vacuum condensing gas hot water boiler to provide heating and hot water for the hotel. The boiler implementing the response to the national policy of environmental protection requirements and local environmental protection departments on a series of low nitrogen emission standard boiler requirements, in terms of design, manufacture, installation and other sectors have strict checks to ensure that the boiler safe and stable operation.Free Chat
