mechanical seals gas fired hot water boiler

the fuel used in the horizontal boiler is natural gas which is transmitted to the boiler room through the gas pipe.The gas is convenient and less pollution. But in the using process, the probable leakage not only increase the fuel costs of enterprises, but also contain security risks, the following is the solving measures proposed by engineer:

1. the natural gas leakage treatment. For outdoor buried gas pipeline leakage, the Gas Co should be immediately informed to cut off the gas source, and the person in charge should report to the responsible departments. According to the natural gas leakage emergency treatment, indoor gas leakage: emergency shutdown, open the emergency air exhaust machine, cut off the total valve of boiler room, and report to the responsible departments, according to the natural gas leakage emergency treatment.

2. strictly regulate the industrial boiler gas design construction, uses the high quality boiler,burner, valves and other accessories, prevent gas leakage, strengthen management, regular inspection, must according to specification of the installation of gas leakage alarm device, and regular inspection. smoking and playing mobile phone in the industrial gas boiler room, no dumping any inflammable and sundries, real domestic demand the use of electric welding, gas welding operations, in strict accordance with the operation procedures, construction work by professional on-site monitoring, all those who enter the boiler room personnel are required to wear anti-static overalls.

4, when the industrial gas boiler gas leaks, gas concentration in the lower explosion limit before also need water spray extinguishing system protection. Using dilution water spray, the gas concentration decreased, can play the role of fire effect. Fire water and fire hydrant in good condition, especially in the cold winter, to prevent the pipeline freezing.

Water wall boiler tube leak or burst phenomenon how to do 1, the normal water flow is not greater than the steam flow. 2, the furnace pressure transient and unstable prejudiced. 3, tube leak detection alarm device. 4, the furnace may not tight at the outward discharge gas and water vapor, and a significant leakage sound. 5, the main steam pressure drop. 6, boiler combustion dark flame instability caused by severe boiler fire. 7, when the induced draft fan is automatically cast, abnormal static vane opening is increased, the current increases. 1 reason, the presence of water wall tube material defects or post-production, the installation of the damaged pipe, poor welding quality. 2, the inner tube fouling overtemperature. 3, the inner tube corrosion. 4, water wall wear. 5, the long-term high load operation, furnace coking, coal sulfur corrosion caused by high temperature water wall. 6, improper combustion, flame deflection. 7, in the possession of bad foreign body, the water cycle. 8, the wall of the long-term over-temperature operation. 9, the temperature difference between waterwall tubes, mechanical stress crack. 10, the normal exit or drain sootblower steam punctured tube. 11, smashed chunks of coke furnace water wall tube or serious explosion occurred, resulting in water wall tube suffered external damage. 12, boiler overpressure long run. 13, the boiler starts to heat up, step-up too fast. 1 process, the leakage should try waterwall tubes outage. The leakage is not serious, while still capable of maintaining operation, note that each of the automatic operation when the device, if not normal, it is cut immediately to the manual, if necessary, may be down, down-load operation. Closely monitor the development trend of damaged parts, good accident anticipation, application shutdown as soon as possible. 2, if the leak is serious, the bursting point temperature after a sharp rise in quality work, leading to serious over-temperature wall, unable to maintain the normal operation of the boiler or threaten the safety equipment, emergency shutdown provision should be processed, when the steam temperature to protect the action value, the protection does not move, should immediately hand MFT. 3, note that the operation of the electrostatic precipitator, to strengthen the inspection checks, to prevent fouling, and the electrodes ESP hopper, pipes and the like plugging air preheater ash. 4, after the shutdown, should retain ID fan, the furnace pressure is maintained constant, there is no discharge to be stopped after soda ID fan.

AMD Power were to buy 10 tons of steam and one 4 tons of steam condensing steam boiler fuel gas from the company for cell processing company production and construction. From the analysis of the demand to the boiler factory, by the company solely responsible for AMD Power fully demonstrated the company's confidence in me, the smooth progress of bilateral cooperation.

The main problems of autonomous decentralized boiler heating mode: 1, "two small" boiler room that is small-scale (10,000 m- for the following boilers 60%), small boiler capacity (single boiler average capacity of only 2 tons / hour). "Two low", i.e. the boiler load is low, the thermal efficiency is low. Calculated heat index 70W / m =, 0.7KW (i.e. 1t / n) for 10000m =, in fact, only for 4000m =, less than half, in the "Mara car" low load operation. Thermal efficiency is naturally low, generally only reach 50-60% oC "two can" That is more than the energy consumption, the existing multi-intermittent heating (burning six hours every day and night, stopping six hours, repeated twice). In the current institutional heating intermittent heating accounted for 82%, only 18% of continuous heating. 2, boiler room hire older workers and the burning of a modern boiler during operation merely by virtue of the experience "the sky light a fire," there is no scientific basis for heating, that is, how many points you cold, warm day less burning point, which is very difficult to achieve the purpose of heating and energy requirements. 3, the heating system is unreasonable, due to some historical reasons causing heating in the system has inherent missing, and in the intermittent heating is due to habits die hard so the resulting decline in the quality of heating also a waste of energy. 4, which is related to the owners and the quality of that set out secretly put a hot water tank, can lead to heat loss, water loss occurs, really makes the heating unit is really a headache, which cause heating problems. 5, since the local heating technology of high and low level, so that in the heating process, the heating requirements for the simple pursuit of the distal end of the owner excessively coal temperature of the heating water, resulting in overheating proximal end, a distal end of the warm unbalance, or warm proximal distal cold conditions, which resulted in a waste of energy, will not help solve the problem. 6, the boiler disrepair, will take place at the junction of the pipeline corrosion, fouling and even the phenomenon is really due to the HVAC heating during water treatment errors caused by, resulting in fouling of the boiler heating surface, or Since the agent is such that the boiler ash surface to form grime, which is management problems. 7, the high heat load design makes enormous waste in financial resources, but also makes the device parameter selection is also too large, the most important thing is a waste of energy. 8, due to improper selection of the boiler supply pump, such that the heat medium low boiler room parameters, the performance of the boiler is low lift, low thermal conductivity, insufficient heating vicious circle. 9, due to the design of overkill situation arise, ie, a single heating boiler can solve the problem, but using a more common heating boiler, resulting in low thermal efficiency of large coal consumption and generate unreasonable conditions. 10 vertical imbalance, if indoor heating system will be conducive to eliminating the balance of water resistance, which requires the designer to identify line) inputs the number of circulating pump is too large, such a large pump flow, low return temperatures, generally in 25 degree. This will increase electricity consumption. 11, about the nature of different heating buildings, commercial buildings and residential buildings if the use of a heating system is the same, then since the days of the commercial building heating requirements of large, large civil construction heating at night, if you can not time-heating, is bound to cause waste of energy. 12, single-tube heating system installed can not be achieved thermostatic valve on the radiator, but now a lot of indoor heating systems or belong to single-tube system, which is not conducive to long-term development. 161, why gas hot water heating boiler heating problems occur each year to slow the heating time, a gas boiler heating the user of the problem in many areas of heating will slow, but the problem is often not the fault based on the boiler itself. In this regard, today we elaborate on the reasons for this phenomenon. 1, because the use of gas-fired boiler heating, after carrying out the heating boiler ignition, but also need to go through the oven, cool-running, heat exchangers and other process, so as to make heating gradually warming. After the gas mechanical seals fired hot water boiler heating during ignition, the oven is ready to work early each year heating must be carried out, a process that takes about 3-5 days to complete. 2, the use of the process, gas hot water boiler also need to go through the process of heat transfer, the temperature will gradually rise. Gas heating boiler heat exchange process is mainly water cycle process, stand out from the hot water not flow directly to the residents of the home heating network, but need heat exchanger unit to transfer heat energy in the hot water heating plant to the residents of the home in the circulating pipe network. 3, starting at the initial stage of the heating boiler, water temperatures of the respective heating stations is not very high, coupled with the complex structure of the network, the gas hot water boiler heating hot water heat exchanger is a process, especially in the end of the pipe network user, heat transfer process will be a little longer time.
