dzl series hot water big volume boiler

When the dzl series hot water big volume boiler after a failure should be promptly dealt boiler, auxiliary equipment occurs due to the abnormal tiny leak or the boiler itself and burn local overheating phenomena, after timely treatment (timely stop or pause), can resume normal operation, depending on the boiler malfunction. After the boiler failure if not promptly treated, may lead to an accident, it must be given sufficient attention. Boiler equipment operation at any time are likely to be some anomalies, but behind these phenomena are often some kind of operating equipment failures and accidents aura. Which in addition to defects in the equipment itself, but also may be due to unskilled personnel to run the operation, negligence or misuse caused. Therefore, the operating personnel not only to master the technique, but also master the basic method to determine fault in order to properly determine and deal with failure, to avoid accidents and reduce losses in accordance with the operation of some of the anomalies. Typically, substantially determine the fault or accident three main methods, i.e., direct analysis method, the indirect method of analysis and synthesis. Direct analysis method is based on boiler operation intuitive phenomenon, with human sensory organs and experience to directly determine the point of failure, which is a basic method. With the growth and continue to accumulate experience in running time, it will use this method skillful. Indirect analysis method is based on professional knowledge-based, to determine the accident or malfunction by the process of logical reasoning under the direct control analysis, familiar with the equipment system premise. To achieve timely detection of faults and correctly determine fault, only to master the direct analysis is not enough, because most failures or accidents, often showing one or more indirect, implicit in the initial phenomenon occurs, it will not It can accurately judge. Therefore, the operating personnel in mastering the direct analysis at the same time, to gradually learn and become familiar with the indirect analysis. Occurs such as when the boiler flue gas temperature is low, the fault can not be determined directly, but indirectly by analysis of the heating surface can reflect a defect. Comprehensive analysis is a direct analysis method and indirect analysis of organically combined. For the gradual failure implicit features, with particular attention to the comprehensive judgment. This method is based on the surface of several phenomena, the main feature to check to find malfunction in the integrated cross several phenomena, determine the nature of the fault and the final position. Then, take appropriate measures to prevent the failure to expand. In short, the operation of the boiler, when the abnormal phenomenon, should find the problem in different ways according to experience, to determine the nature and location of the fault. In the current, the more Instruments, higher degree of automation, the operator can find signs of failure or an accident situation by displaying the instrument, and then checked again to confirm targeted fault location.

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.
