When selecting and purchasing hebei sunhouse stove and boiler manufacturing co ltd sensors, we should consider which types of boiler sensors should be determined according to the measuring object and the measuring environment. The principle of the sensor must be considered first, which requires an analysis of various factors before it can be determined. According to the characteristics of the sensor to be measured and the conditions of use of the sensor, consider the following specific issues, the size of the measuring range, the measured position of the sensor volume requirements, the measurement mode of contact or non-contact, the method of signal extraction, Wired or non-contact measurement, the source of the sensor is imported or home-made and many other factors. The second is the choice of the sensitivity of the boiler sensor, usually within the linear range of the sensor. The higher the sensitivity of the sensor, the better, when the sensitivity is high, the output signal corresponding to the measured change is larger, which is beneficial to signal processing. The sensitivity of the sensor is directional. The sensor with low sensitivity in other directions should be selected when it is a single vector and its directivity is high. If the sensor is measured as a multi-dimensional vector, the lower the cross-sensitivity of the sensor is, the better.
What do I need to install a new hebei sunhouse stove and boiler manufacturing co ltd and boiler room design content: about difficult problems boiler, which is very large, so below, it may be difficult to answer their questions, so that we become more familiar with this website boiler products, but, question and answer to form, it can also enrich everyone's learning style, learning to get good results. 1.

The 35 tons of boiler, which is equal to 24.5MW boiler. 2. The new boiler installation, must provide what information? Installation of a new boiler, the information it needs, there are mainly the following, for: (1) pattern a boiler, the boiler comprising a general view, installation diagram, FIG coefficient of thermal expansion, and the boiler water system of a pressure-receiving member and FIG FIGS. Also, a discharge amount of the pressure relief valve member and the calculations, calculation results or the summary. (2) the quality of the product documentation, mainly for product certification, quality assurance and monitoring inspection certificate, as well as non-destructive testing and reporting energy efficiency testing these reports. For manufacturers, but also a copy of the manufacturing license. (3) If, boiler pressure greater than 38MPa 98MPa or less, also requires heat, thermal wall temperature, smoke wind resistance of these three calculations or results summary. If, boiler pressure greater than 98MPa, then, in addition to these, also need to provide water circulation calculations.
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.
How hebei sunhouse stove and boiler manufacturing co ltds and furnaces and bath boiler tubes What are the requirements? Boiler and furnace, which is what you need to know? About boiler, which related to difficult problems, not in front, but the urgent need to know and understand? Ask these questions, its main purpose is to be completely resolved, thus, help you to successfully use the boiler, and then, get good use of effects and economic benefits. 1. boiler and furnace, what should it be? Boiler and furnace for a specific process is as follows: first steam valve and opens slowly, not too fast to avoid problems such as instability vapor pressure, then, two boilers are coordinated and slow overload. If in the process, risk factors found to affect the safe operation of the boiler, then it should stop immediately and steam until after the elimination of these negative factors, then steam and work. Also, pay attention to adjust the water level in the steam load is moderate, not any problems. 2.G1, G2, etc., specifically refer to? Central boiler furnace temperature is generally controlled to what extent? G1, which refers to a stoker boilers, G2, refers to two stoker boilers. And so on, G3 refers to three boiler fireman. The reference standard for TSGG6001-2009 "boiler safety management and operational personnel examination outline." As for the center temperature of the boiler furnace, under normal circumstances, it is controlled in this range 900 ℃ -1100 ℃. 3. bathing in the boiler tubes, what requirements? In addition, the auxiliary boiler, which is the general concept of it? Boiler tubes in the bath, is not predetermined portion of its media activities, media emptying can then be emptied as far as possible, can not be emptied, it should regularly discharge or take microfluidic way to avoid frozen pipes this problem occurs. The auxiliary boiler, which is a general concept, therefore, on the issue of two, whose answer is yes. Further, in the upper part and which apparatus comprises means, there are many, here, not one is illustrated.
