Electric boilers and power consumption advantages and what about the gas boiler: the boiler, it contains content knowledge, there are many, and, associated with difficult problems, but also have a lot, so below, you may wish to adopt a question answer this form, answering questions for everyone, and thus, there is a good learning effect, this also allows us to own, from a new harvest, and to make progress and development. 1.70MW and boiler 100t / h boiler, which is the same as you? This problem, in the boiler manufacturer boiler box appears, is not difficult to answer, so they give specific answers, is: 70MW boiler 100t / h boiler, two boilers, if, from a conceptual point of view, then then, they are the same, because the total for the heat, is the same. However, for the type of boiler, there may not be the same. The former, there may be hot balance type water boiler for singapore, while the latter, there may be a steam boiler.
Check the work before the start fuel gas-fired boiler in order to protect the safe operation of the gas boiler, improve operational efficiency boiler, make sure to check the work before the boiler starts, every detail can not be ignored. 1, check the safety accessories, thermal instrumentation, electrical instrument should be intact; 2, check the connections, whether the water leakage and the furnace body line; 3, check the waste line, the water line, return line should be smooth; 4 , should check the line voltage is 380V, the fluctuation should be within ± 5%; 5, oil-fired boiler and a filter pump check whether normal oil, gas boiler check the gas pressure is normal, not too high or too low, the oil supply opening valves; 6, check whether the pump Sheung Shui, or opening the purge valve, until the Sheung Shui so far. Water Supply System opens each valve (including the water pump and water valve before and after the boiler); 7, check level gauge, the water level should be in the normal position, to prevent false water level, if the water can be manually Sheung; 8, check the pressure conduit the valve must be opened, the wind deflector must all flue opening; 9, each knob inspection control cabinet are in their normal position; 10, a check valve should be steam boiler in a closed state, the hot balance type water boiler for singapore circulating pump valves should be closed state; 11, check water softening equipment is operating correctly, create a variety of indicators of soft water meets national standards. Carefully do the above inspection, the basic conditions for the fuel gas boiler safe and economic operation.
In order to promote technological progress and sustainable development, improve environmental quality and protect public health, recently, the Liaoning Provincial People's Government of air pollutants for coal-fired power plants developed specific criteria (hereinafter referred to as the "standard"). This is the first time a set of policies Liaoning Province for air pollutant coal power plant.
"Standard" provides for pollutant discharge limits, surveillance and monitoring requirements within the jurisdiction of coal-fired power plant in Liaoning Province atmospheric and fugitive emissions control requirements. Since the implementation of the standards, air pollutant emissions coal-fired power plants all within the jurisdiction of Liaoning Province will be executed in accordance with the provisions of this standard.
2, since January 1, 2019, the emission limits of existing single output and more than 300MW generating units supporting the provision of a coal-fired power generation boilers execution table.
3, since 1 December 2020, the emission limits of existing single output 300MW generating units supporting the coal-fired power generation boilers and other power boilers as specified in Table 1 execution.
Sampling the exhaust gas (1) power plant, to be carried out in a predetermined position in accordance with the type of monitor emissions monitoring contaminants. In the discharge of pollutants should be set up to monitor the position of long-term monitoring holes, sampling platform and related facilities. When the sampling platform height from the ground greater than 40m, should be set by a lift platforms, lifts or other convenient and safe facilities. No elevator or elevator building coal-fired power plants, when the sampling platform height from the ground greater than 20m, should be set up safe, convenient electric monitoring equipment hoisting facilities.
Composition structure (3) continuous monitoring system atmospheric pollutants, technical requirements, test items, test methods and installation, commissioning, acceptance, operation management, data processing, etc. according to the provisions of HJ75 and HJ76.
(5) continuous monitoring system meter of air pollutants detection sensitivity, detection limit, and should meet the range of low concentrations of pollutant emission monitoring technical requirements, the concentration of nitrogen oxides include nitric oxide (NO) and nitrogen dioxide (of NO2), Determination of nitric oxide only has the ability to configure the analytical device of nitrogen oxides NO2 / NO converter.
(7) for coal-fired power boiler emissions of air pollutants sampling monitoring, sampling frequency, the sampling time and the operating load requirements,, HJ / T397 and related predetermined low exhaust gas concentration monitoring is performed according to specifications GB / T16157.
(9) shall be in accordance with the provisions of the enterprise "Environmental Monitoring and Management Measures" and the HJ819, HJ820 requirements of pollutant emissions and its impact on environmental quality around to conduct their own surveillance, monitoring and save the original records, public information.
Determination of air pollutants fired power plant analysis are shown in Table 2. After the release of the present embodiment national standard method of monitoring criteria pollutants, such as applicability to meet the requirements, the same applies to the determination of the corresponding standard contaminants present.
2, responsible for overseeing the management of this standard by the executive authorities and the standardization of administrative departments above the county level environmental protection. The results of the environmental protection departments at all levels and other relevant units in the enterprise supervision and checks can be instantly sampled or monitored the scene as determining whether acts of sewage meet emissions standards based on the relevant environmental protection and the implementation of management measures.
Common hot balance type water boiler for singapore Accident (c) hot water boilers common accidents in addition to accidents, explosions, that there is a tube rupture. So what causes hot water boiler tube rupture is what kind of solutions does the cause of the hot water boiler tube rupture:?? Quality (1) boiler water is poor, resulting in the accumulation of impurities in the boiler, severe corrosion and other problems attached boiler tubes, not a long time to clean up in time, lead to the phenomenon of burst pipes. Material selection (2) non-compliance boiler tubes and so lead to pipeline pressure less able to cause the occurrence of burst pipes phenomenon. (3) In addition, due to the boilers used for a long time, parts of aging, wear and other phenomena more serious, there will be burst pipes phenomenon. (4) When pulverized coal boiler, oil, gas hot work, operational errors can cause the collapse of the furnace walls and furnace tube bore explosion. Solution: (1) timely boiler attached to the wall of debris to clean up after the shutdown. (2) severe damage to the superheater, boiler shutdown immediately related operations hot water, and then timely maintenance. In short, boiler tube rupture is one of boiler accident hazards of large accidents, hot water boiler during operation, should be timely maintenance, to avoid unnecessary security risks.Free Chat
