Horizontal Fire Tube Oil Fired Hot Water Boiler for Hotel

The main difference between the fuel gas boiler thermal control of the basic requirements of fuel gas boiler room in claim 1. The thermal control of the basic fuel gas boiler fuel gas boiler main features of the gas boiler grate firing combustion system is different in that, mainly in the nature of the fuel and combustion different. Fuel gas boiler combustion system has the following two characteristics: 1) If not properly controlled combustion process, the furnace can form a large number of combustible gas mixture, when mixed gas deflagration, the furnace may cause an explosion, causing heavy casualties and property losses. 2 combustion) of fuel gas boiler combustion space, the combustion speed, load responsive. 2. controlled boiler fuel gas and fuel gas requirements of the boiler combustion system adapted to, the following basic requirements for the fuel gas boiler automatic control system: (1) reliable system configured to prevent fuel gas boiler explosion, the design of the fuel gas boiler when automatic control system must be designed to give priority to the reliability of a system, the detection system may employ protective control system provided separately, if necessary. In the selection of microcomputer control system, it is necessary to adopt a dual configuration instructions manual and the necessary back-up of important parameters such as measures to improve the reliability of the control and protection systems. (2) starting the program control strict fuel gas boiler shutdown should process control, rigorous testing of the fuel during the start-stop system, air supply system and a flame monitoring system, since a failure to avoid the shutdown process. (3) timely protection should be reported depending on the circumstances, the choice of the following associated with the combustion system alarm and interlock protection projects: 1) drum level limit alarm and interlock protection. 2) Overpressure drum (temperature of hot water for boiler overtemperature) alarm and interlock protection. 3) flameout interlock protection. 4) Low oil pressure interlock protection (oil-fired boiler). 5) high oil temperature interlock protection (oil-fired boiler). 6) low oil temperature interlock protection (oil-fired boiler). 7) Low gas pressure interlock protection (gas boiler) 8) Interlock high gas pressure (gas boiler). 9) wind down interlock protection. 10) Burner flange interlock limit switch. 11) combustible gas leak alarm. 12) earthquake interlock protection. (4) a fast system response when running the fuel gas boiler abnormal combustion flame is off, the automatic control system required to be quickly cut off the fuel supply, to prevent the fuel into the furnace, thus requiring automatic control system fast enough response speed. (5) When the load adjustment linkage fuel gas boiler load changes, fuel regulator response speed faster than the response speed of the air supply system. When the load suddenly increases, the rate of increase of fuel greater than the corresponding rate of increase in the amount of air, resulting in incomplete combustion, soot is produced; when the load is reduced suddenly, fuel reduced speed, resulting in high oxygen smoke. For small boiler-off control of combustion increase or decrease should match the amount of increase or decrease in the wind, or it may cause flameout. Thus in the design of automatic control system, should be considered synchronized adjustment of combustion air. (6) field instrumentation for explosion-proof gas boiler automation systems, field instrumentation should be used in explosion-proof instrument.

Oil-fired boiler maintenance methods "" A lot of companies because after the purchase of oil-fired boilers, Careless maintenance process, with the result that the useful life of oil-fired boiler is greatly reduced. So how should it be maintenance of the oil-fired boiler? The following article gives you a detailed analysis. After conducting oil furnace shut until the furnace cooled water to the boiler water below 70 ℃ exhausted, the internal completely remove the dirt, washed away, all manholes, hand holes, valves and other pipeline tight blockade, and with a blind plate and running boiler completely isolated. After all of the alkaline solution is added, and then injected into the soft water boiler, until the water coming out from the highest point till the boiler, the water supply valve is closed, note that the average mixing an alkaline solution inside the boiler. Stop oil-fired boiler more than a month, maintenance of law should be dry, wet maintenance shutdown method can be used the following month. To schedule the maintenance period Microflame oven, schedule the water cycle, the concentration of the alkaline solution throughout the same. Every five tests also take a basic solution, such as alkalinity less than 5-12mmol / 1 solution should be applied. Periodic inspection outage before the oil-fired boiler furnace, should be prepared to work the following three aspects: (1) review the registration technical dossier furnace boiler and boiler furnace usage understand. In order to fuel the transformation within the furnace boiler external inspection be aware, the general need to understand: the transformation of the electric furnace boiler design, manufacture, installation; boiler furnace revamping; boiler furnace use history and usage; boiler furnace water treatment case ; boiler performance and other rules and regulations. (2) Check before shutdown preparation. First, with the production schedule maintenance shutdown date, and then let the transformation of the normal furnace boiler shutdown program shutdown, but slowly disheartened. Injecting cooling method may be employed downcast water, replacing the water cooled furnace and the furnace into line ventilation cooling. When the boiler water temperature was reduced to 70 ~ 80 ℃, before drainage. Open all doors hole. When the door opened, to prevent warm water, steam jet man suddenly burns. Corresponding to the passage blocked pipe on the transformation test furnace boiler steam, water supply, sewage and other pipes and other run in the transformation of the electric furnace boiler. Blocked with shutter have sufficient strength to avoid being broken drum high pressure medium. To clear the blocking position is indicated. And other operational boiler furnace flue should be communicated reliably cut off. Also to clear the transformation of furnace soot and scale boiler by warm surface. (3) test preparation tools and lighting. In order to ensure the smooth entry inspection, the inspector should prepare the necessary equipment, tools, measuring tools and safe and reliable lighting devices.
