Boiler equipment quality appraisal

Boiler equipment is an energy conversion equipment that transfers thermal energy to water or other working media by burning fuel, electricity or other energy sources to generate hot water or steam with certain parameters. The boiler is mainly composed of two parts: the "pot" and the "furnace". The "pot" refers to the steam-water system of the boiler, which is used to generate steam or hot water, and the "furnace" refers to the combustion system, including wind smoke and combustion systems. The boiler unit includes components such as the furnace, flue, heating surface and furnace wall, while the ancillary equipment usually includes a blower, induced draft fan and fuel preparation system. Boilers are widely used in industrial and civil fields, such as thermal power stations, ships, locomotives, and industrial and mining enterprises, providing power and energy for these fields.

Zhongke Testing provides boiler equipment quality appraisal services.

Boiler equipment quality appraisal can be analyzed from the following aspects:
1. Check design documents: Check the design documents of the steam boiler, including design drawings, calculation books, construction drawings and other documents, to confirm whether they meet the requirements of national and local regulations, standards, and specifications.
2. Check the manufacturing license: Confirm whether the manufacturer has obtained the national special equipment manufacturing license, and verify whether the relevant information on the license is consistent with the actual situation of the steam boiler.
3. Check materials and parts: Check whether the materials and parts used in steam boilers meet the requirements of relevant standards and specifications, including material, strength, size, etc.
4. Carry out appearance inspection: Check whether the appearance of the steam boiler is complete, without damage, without obvious deformation, etc.
5. Carry out a water pressure test: Carry out a water pressure test to test the sealing and pressure resistance of the steam boiler to confirm whether it can operate normally.
6. Check the ancillary equipment: Check whether the ancillary equipment of the steam boiler, including safety valves, pressure gauges, water levels, drain valves, etc., are complete, intact, flexible and reliable.
7. Conduct a safety assessment: Carry out a safety assessment of the steam boiler to evaluate its safety performance under normal use, including temperature, pressure, thermal efficiency, etc.
boiler equipment quality appraisal requires comprehensive consideration of all factors, and in practical applications requires customized analysis based on specific circumstances.

A certain court entrusted our company to conduct quality appraisal of the "boiler" involved in the case, and identify and analyze whether it was a special boiler for yellow phosphorus exhaust gas. After receiving the entrustment of quality appraisal of the "boiler" involved in the case, our company selected experts with many years of experience in the boiler industry to form an appraisal expert group based on the specific circumstances and technical requirements of the case. Under the organization and coordination of the client, our company's project personnel and appraisal expert team went to the location of the "boiler" involved to conduct on-site inspection work. The results of the quality appraisal of the "boiler" involved in the case are as follows:
Based on the existing information and the existing status of the "boiler" involved in the case, it cannot be determined that the "boiler" involved in the case is a special boiler for yellow phosphorus exhaust gas. The composition of the anti-corrosion coating used in the "boiler" involved in the case was inconsistent with the test report provided by the supplier, and there were quality issues.
The materials used in the "boiler" involved in the case do not fully comply with the contract requirements, and there are problems with material selection.
The "boiler" involved in the case has not been installed yet and is not ready for startup inspection, so its performance and safety cannot be evaluated.
