A boiler operation must be controlled and stable operation of secondary causes of boiler steam temperature control stability of a secondary steam temperature has important implications for safe and economic operation of the unit. When the steam temperature is too high, it can cause overheating, a portion of the metal to reduce the strength of the reheater, and the steam turbine pipe cylinder and a rotor, resulting in shortened life of the equipment. Severe over-temperature, it will also enable the heating surface blasting. When the steam temperature is too low, the effect thermodynamic cycle efficiency, and a steam turbine final stage blades at excessive humidity, severe water hammer may occur, resulting in damage to the blade fracture accidents. When the steam temperature substantially sudden rise dump, large thermal stress is generated in addition to the heating surface of each weld and the outer part of the boiler is connected, will cause the relative displacement between the cylinder and the rotor of the turbine increases, i.e., the expansion difference increases, severe or even static friction wheel and the separator, causing severe vibration. In addition both sides of the turbine steam temperature deviation is too large, both sides will uneven heating turbine, uneven thermal expansion. Therefore, the operation of the boiler steam temperature to closely monitor, analyze, adjust, control steam temperature stability with the most reasonable method.
Common methods of water quality testing methods commonly used in industrial boilers which industrial boiler water quality testing of water quality testing methods which are commonly used in industrial boilers which (1) comparative analysis. Industrial boiler water quality testing will generally take two comparative analysis. The first analysis method is to compare room. Indoor contrast mainly through the contrast between the contrast between people or equipment. The second method is to compare the laboratory analysis. This method is mainly for comparison and testing personnel random error, system error. (2) review sample. Water quality sampling, number, checking and retention, and then returned to retest samples deputy members. Deputy sample prior review, to be processed. Environment and pay attention to time during retest retest sample, so that the processing result can be obtained twice, and then the results were compared. Sample analysis (3) in parallel. When parallel samples for monitoring, to ensure that each batch of samples will be monitored. Determining the actual number of replicates the number of samples so that it can effectively ensure that the number of replicates measured more reasonable. Also setting it within a reasonable range. (4) control a calibration curve method. The calibration curve using the control method can make the results more accurate. First, the calibration curve Control Act mainly a combination of a certain time period, so that the result will be more timely and effective, precise terms, generally to a calibration curve based on monitoring of time each batch of samples. Second, to ensure the accuracy of the calibration curve, it can really play to monitor the effect of the sample.
Battle blue horn sounded, emissions of sulfur, nitrogen and oxygen compounds gradually strict national requirements. To improve the quality of the environment, but also the people a blue sky, in all industries around the environmentally friendly product revolution, Hainan Sinochem Pharmaceutical companies are no exception. By the company investigation and comparison of boiler products, in March 2017 signed a six-ton steam-cleaning integrated condensing gas boiler and steam fast boiler. Tested and post feedback, the boiler equipment installation qualification, operating normally, and successfully passed the inspection by local quality inspection departments of the boiler.
Condensing boilers can be used in enterprises, hotels, military, railway stations, airports, factories, hospitals, schools and other occasions. Its main use features are: high thermal efficiency - more money; exhaust gas temperature is low - more environmentally friendly; output medium temperature - good steam / hot water quality; high safety factor - once an exception occurs immediately start the alarm system.Free Chat
