City Horizontal Cooperation fuel oil wns hot water boiler manufacturer how much the RMB against you in the process of selection of hot water boiler fuel, will be exposed to many questions. Here, we analyze them with you. Hot water boiler fuel prices are a hot water boiler fuel price, the price of the burner as well, accessories (pump, control panel, the entire valve) synthesized in price. Determine the root causes of hot water boiler fuel prices, probably produced in the included: no similar name, manufacturer, production capacity method, testing, planning, steel and other election. Among the most focus on the root causes are listed below: a, factory productivity of plant productivity, will decide the level of goods. The reason is that a productive company, remove occupied a relatively large amount of industry, with a full skill experience. Secondly, what is the professional product design capability. The degree of planning to compete for the impact of commodity standards are very large. Affected, household commodities reliability, energy savings, reliability, and convenience standards. b, choose steel standard specification steel, commodity production is the ability to focus. Professional standards steel, is to ensure stable oil hot water boiler tightness bear fruit. There are some second-tier brands used does not meet and do not meet the standard steel plate, hot water boiler fuel will cause commodities, poor reliability, high energy consumption, so there is reliable inconvenience for customers, for example, even if the cost of saving the time of purchase, but in addition to Pearl bomb bird. C, automated production equipment production capacity of standard fuel hot water boiler production and processing time of welding, coil, cut, most focus method. These three methods, than workers to operate, the use of automated production equipment production capacity, the advantage is very obvious. The reason is that automated production, with increased precision, minimal fault. This is the big name oil hot water boilers merchandise, better than the name of the key root causes small. The reason is that its production capacity results, but then closer degree of planning, easy to achieve the standard requirements. Step ④, test some of the Chinese market companies, often not subject to the harsh hot water boiler fuel commodity, factory evaluation process evaluation. Manometry end, even for specialized merchandise. This is certainly a very serious responsibility to fulfill. Professional test step, should Baoyun: load verification, validation inert gas, seam welding test, the degree of sealing of the test, there is a trial period cycle. Essential, indispensable. Only so, we can ensure the delivery of professional customers products so that customers in Japan to use the process, reduce the goods in question, affecting the customer's daily production activities. 5, service level most of the second-tier brands, it is no after-sales service. Sale are as commissioned agents. However, most of the agents, no professional team of professionals. After the problems will occur again and again passing the buck, and are often unable to clean up the consequences. Above, that is, hot water boiler fuel prices, the impact of the roots. Normally, there is strength, excellent fuel commodity prices hot water boiler, oil hot water boiler plus burner, almost 700 kilowatts, 100,000 or so.
Solutions and prevention of gas oil-fired boiler flameout Today we'll resolve what about gas fuel boiler flameout solutions and prevention fuel gas-fired boiler flameout Solution: First, the furnace pressure gauge indicates the value suddenly increases, the furnace black can not see the flame, burning furnace sounds disappear, extinguishing the flame supervision devices emit a signal; the temperature dropped sharply atmospheric pressure, the water level dropped after the first rise, and so are flameout phenomenon. Auxiliary flame caused by an accident, such as a fan, blower power interruption, there is an accident signal emitted; fuel supply as a result of intermittent, the boiler is oil or gas pressure drops to zero, only a single burner flame, the furnace may also be thrown skew central flame extinguished burner pressure change; as a result of the fuel supply interruption, the extinguished burner pressure or hydraulic indication may drop to zero, and the fuel consumption, the gas pressure is increased other operating burner. Causes gas boiler flameout are: sudden increase in gas pressure caused from the fire, the solenoid valve malfunction the gas supply interruption, the gas composition has changed so much moisture content is too high and so on. Blower, fan failure, the load is too low furnace pressure is too large excessive leakage and other excessive wind, so that the furnace temperature is too low can also cause the boiler flame. Cause misfire has oil-fired boiler: oil pump failure, the oil surface is exposed inhalation tube, clogging of the oil filter or oil supply pipe, a solenoid valve malfunction or misoperation caused by oil running intermittently. During transport the fuel with steam by heating water; inappropriate position inhalation tube with the pumping of water; improper contaminated oil floating on the water; poor dewatering tank drain plug such that the fuel with water. After the explosion should be taken to prevent the furnace boiler flameout, it must immediately cut off the fuel supply to the furnace, and then block the electromagnetic valve of the gas supply valve to seal off the fuel supply to run the burner. When the action to be fast in order to avoid inheritance or restore fuel supply during operation, causing the furnace explosion. And identify the cause of boiler flameout troubleshooting find a good job and then start the preparatory work. Before starting the boiler should be enhanced ventilation purge, purge time is more than 5min, then procedures ignition. It is forbidden to send fuel directly to the high-temperature furnace without using an ignition spark ignition device to prevent furnace explosions. If due to fan failure caused when the flame should be quickly cordoned off the fuel supply line of each valve, with special attention because the valve is not tight blockade caused by leaking fuel. Ventilation and purging of the furnace and flue in accordance with the approach of an emergency shutdown. Ignition step by step in the recovery operation after the fan. Single burner flame burner only block the fuel supply valve, the burner off a small damper identifying and troubleshooting and then re-ignition by the ignition process. Boiler flameout of prevention: For oil-fired boiler should minimize the possibility of fuel transport, storage and handling of water in all sectors. Tank initiative measures should dehydration and dehydration on schedule. In any case, it should ensure the security of oil supply. The supply of oil and acceptance testing, cutting oil change when the master species. When a large change in oil types, varieties and the need for the oil tank to store the original varieties contaminated test to determine whether the same storage tank, to prevent the density and viscosity differences between a large number of decomposed oil mixed insoluble material, clogging oil pipeline. For the operation of the gas boiler should be closely monitoring the evolution of gas pressure, the timely processing of exceptions thrown up air pressure, ensure the supply pressure in the normal range. To always understand, repair gas composition, gas composition changes when large, to take the necessary adjustment measures on the boiler operation.
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.
