Coal quality testing equipment | Coal quality testing equipment | Coal testing equipment | Determination of coal testing equipment standards
1. The coal chemical lab workers are neat and tidy, and they have effective certificates.
2. Before the test, all inspections and corrections must be made to the coal quality testing instruments and coal quality testing equipment used, and the original records used should be ready to meet the test requirements.
3. When using automatic industrial analyzers for industrial analysis of coal, implement GB 212-2008 "Methods for Industrial Analysis of Coal."
4, in the use of automatic moisture analyzer to do the analysis of coal moisture, the implementation of GB/T211-2007 "measurement method of total moisture in coal."
5. When using a calorimeter to measure the calorific value of coal, perform GB/T213-2008 "Measurement of calorific value of coal". Before operation, check whether the oxygen pipe joint is firm and correct the water equivalent according to room temperature and seasonal changes. If there is any abnormality in the results, use the standard sample for proofreading to find out the reasons. Otherwise, it is forbidden to conduct tests and report the results.
6. When using the sulfur analyzer to measure total sulfur, perform GB/T214-2007 "Measurement Method for Total Sulfur in Coal" and verify the total sulfur test equipment with a standard sample every quarter.
7. When determining the specific gravity, perform GB/T217-2008 "Determination of true relative density of coal".
8. When industrial analysis of coal is performed and samples are sent to the smart muffle furnace, personnel injuries caused by deflagration of coal samples and equipment burns shall be prevented.
9. After the test is completed, the desiccant must be placed inside the balance to ensure that the balance is dry and that wet and corrosive items are not allowed to be weighed with the balance. When the scale is weighed, overloading is strictly prohibited.
10. When the test results are collated and analyzed after the end of the test, if abnormal test results are found, standard calibration equipment must be used. If there is an error between parallel samples, the third determination must be performed.
11. The test results must be clear and accurate after finishing, and it is forbidden to alter test results.
There are risk factors and preventive measures in this trade:
1. Detonation of coal samples, poisoning of drugs, release valves, etc.
2. If the ash content of the coal sample is low and the calorific value is to be generated, the sample must be wrapped with the trial lens and then be operated to prevent the coal sample from splashing when it is ignited.
3. When using sulfur analyzers to make total sulfur, it is necessary to fulfill the system of drug use. The drug should be designated as a person responsible for safekeeping and returned after use.
4. In the process of calorific use of calorimeter, it is necessary to strictly implement the cylinder use system, and it is forbidden to aim the vent valve at yourself and others.
The coal chemical testers of the coal preparation plant must pay attention to the safety operation rules of the above coal quality testing equipment when using coal quality testing equipment or coal quality testing equipment. Welcome to consult.
