Thermal oil boiler quality appraisal

thermal oil boiler is an efficient, safe and environmentally friendly heating equipment, consisting of a drum, furnace, burner, heat exchanger, etc. Its working principle is to use the heat generated by fuel combustion to heat the thermal oil to the required temperature, and then transport it to the heat-using equipment.
thermal oil boiler is characterized by its high efficiency, safety, environmental protection, and wide range of applications, such as chemical industry, printing and dyeing, papermaking and other industries. In the future, thermal oil boilers will be used and developed in more fields.
In the case of thermal oil boiler quality appraisal, Zhongke Testing can provide thermal oil boiler quality appraisal services.

The plaintiff signed an "Equipment Purchase and Sales Contract", "Technical Agreement", and "Installation Agreement" with an industrial and trading company respectively. The contract stipulated that an industrial and trading company would provide the plaintiff with a 3T thermal oil furnace and supporting burners, and agreed on technical requirements and related installation and commissioning issues. During the boiler debugging process, the boiler exploded and two employees of the plaintiff company, W and Z, died.
was entrusted by the court to conduct an appraisal and analysis of the "cause of the boiler explosion" of the thermal oil boiler involved in the case.
identification and analysis results:
The identification and analysis expert group discussed and conducted a comprehensive quality and technical analysis on the relevant information and on-site investigation of the thermal oil boiler involved in the case, and made the following suggestions and conclusions:
1. No quality defects related to the deflagration accident were found in the boiler.
2, the supporting burner has design and quality defects, which leads to safety hazards in the burner and is the direct cause of the boiler deflagration accident.
3, poor fuel oil stability and improper operation are also related to boiler deflagration accidents.
