catalogues of water oil boilers used in hvac
How to maintain the boiler during operation of the boiler during operation how to maintain water supply and water quality monitoring furnace boiler feed water and boiler catalogues of water boilers used in hvac maintenance ⑴ should be consistent with GB / T1576-2008 "industrial boiler water quality" standards. And regularly sampled for testing. The number and frequency of emissions is determined by laboratory personnel. Laboratory and sewage should be detailed records. ⑵ mechanical rotation monitoring for pumps, fans, pumps, etc. to be employed a method of three touch see two monitors. Abnormal phenomenon, that approach to take. If necessary, to shutdown maintenance, are not the effect. ⑶ daily oil tank oil level monitoring if no automatic control device, the oil level should be checked regularly and found that the oil level is too low, the use of two hours is not enough, please notify the staff in advance of the fuel injected new fuel. ⑷ soft water tanks commonly used to control the operating state of the automatic control device ⑸ To periodically check the water treatment apparatus to the ion exchanger is failed, or periodically backwashed. ⑹ monitor the exhaust gas temperature under normal circumstances, the new boiler is generally lower exhaust gas temperature, with the increase in run time will gradually increase. If it is found that the change is too large and exceeds 20 ℃ (algebraic difference), you should select the appropriate cleaning shutdown time. If this phenomenon occurs very frequently, it will have to check whether the normal combustion system. The oil pressure is too low, resulting in poor atomization low oil temperature, oil or wind than not, resulting in poor fuel air mixture so that the char combustion analysis hypoxia. Further, the dry back boiler, if the exhaust gas temperature increased abruptly, it is possible to return in a compartment between the second and third after the smoke box backhaul firewall leak smoke, shutdown would need repair.
After the boiler put into use, such as the hotel responsible person to give us feedback: fast boiler advanced product design, simple and intuitive operation, the most critical is energy saving, low NOx emissions, can be used in the Beijing area. Compared with other boiler brands, fast Boiler made us worry. --customer feedback
Structure and characteristics of Water Tube Boiler (double Longitudinal Tube Boiler)
The structure of the double vertical tube water tube boiler is mainly composed of upper and lower vertical tube, convection tube bundle, water wall tube, header box and down tube and other pressure-receiving components. The length of the lower drum is about half shorter than that of the upper drum. The empty space is provided with a furnace, a curved water pipe is arranged between the two drums, and a water wall tube is arranged around the furnace. The burning equipment adopts a gas/oil burner, and the tail flue has an economizer. The boiler evaporation is generally less than 20 tons / hour (t / h), the working pressure is less than 2.5 MPa (MPa). The high-temperature flue gas enters the rear convection flue from the right exit of the furnace, flows in an S shape along the two smoke-proof walls, flushes the convection tube bundle laterally, and then flows through the economizer from the left side of the furnace wall, and is discharged by the induced draft fan and the chimney.
Two of the three types of protection devices What is the difference of fuel vapor steam boilers and boiler fuel gas steam boiler steam boiler fuel for steam boilers, steam boilers or fuel oil-fired boiler is in, no matter which argument, are refers to this kind of boiler fuel steam boiler. 1. the type of fuel steam boiler fuel steam boiler, which in general, can be divided into both established and horizontal. Vertical fuel steam boiler: the combustion engine, generally use the set in this manner, and using two-pass configuration, so that complete combustion can be performed. In addition, the use of these forms, the stability of the operation of the boiler, it is also very beneficial. The advantages of vertical steam boiler fuel, mainly for high thermal efficiency, and can reduce costs. Horizontal fuel steam boiler: the structure, using a three-pass tube pyrotechnic this configuration, pressurized combustion chamber so that combustion, thereby reducing the combustion load, and reduce exhaust gas temperature. As a result, promote energy conservation, economic performance of the boiler. Further, since the waveform of threaded pipe and furnace thermal efficiency of the boiler can be remarkably improved, and the use of time can be increased. 2. The fuel vapor pressure protection boiler controller: generally this type of high sensitivity, is mainly Zidongkongzhi or chain protection. And may be adjusted according to actual operating pressure of the boiler, so that appropriate. Flame protection: in the main burner, a flame failure protection devices. Its role is the amount of fuel steam boiler combustion is detected, when abnormal combustion, can take immediate steps to make the boiler stopped working in order to avoid some of the adverse consequences. Self-locking power failure protection: Usually burst power for this case the use of the protective device, so that when a sudden power failure, the fuel steam boilers can immediately shutdown and self-locking. Note, however, that when power is restored, the boiler will not start on its own, it must be reset after unlock, boiler to start the ignition and start working. Fuel gas steam boiler and the steam boiler distinction fuel gas steam boiler and a steam boiler, as energy saving device belong to the combustion products of carbon dioxide and water, will not pollute the environment. Oil-fired boiler and gas boiler biggest difference is the use of different fuels, gas boilers use natural gas, city gas as the fuel, light oil, heavy oil-fired boiler is used as fuel. In contrast gas boilers, boiler fuel cost is much higher than gas boilers, therefore, those commonly used in the oil-fired boiler operating conditions of enterprises do not have a gas boiler or Shiyedanwei use. The difference between the fuel and gas steam boiler steam boiler: 1, fuel different: the former light oil, heavy oil as a fuel, which uses natural gas, city gas, liquefied petroleum gas as fuel. 2, the burner different: the former use of oil burners, gas burners later use. 3, different cost: the former high cost, about 1-2 times the cost of the latter. The same point of the fuel gas steam boiler and a steam boiler: 1, the same boiler: the same tonnage same steam boiler or hot catalogues of water boilers used in hvac of the boiler body. 2, the same auxiliary components: in addition to the burner, auxiliary oil-fired boiler and gas boiler accessories equivalent tonnage same. 3, the same production process: The process of production and processing were carried out in accordance with the same process and production standards.
