Boiler quality appraisal

Boiler is a kind of energy conversion equipment. It uses the heat energy released by fuel combustion or heat energy from other sources to heat water or other working fluids to a certain temperature and pressure to generate steam or hot water. The hot water or steam generated in the
boiler can directly provide the required thermal energy for industrial production and people's lives. It can also be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers, which are mainly used in daily life and also have a small amount of applications in industrial production. Boilers that generate steam are called steam boilers, often referred to as boilers, and are mostly used in thermal power stations, ships, locomotives, and industrial and mining enterprises.
In boiler quality appraisal cases, Zhongke Testing can provide boiler quality appraisal services.

Boilers can be divided into natural circulation boilers, controlled circulation boilers and once-through boilers according to the circulation mode.
boilers can be divided into stratified combustion boilers, suspended combustion boilers, cyclone combustion boilers and circulating fluidized bed boilers according to combustion methods. Among them, the common flame types of suspended combustion boilers include tangential, wall and hedging, U-shaped, W-shaped, etc.
boilers can be divided into Π-type (inverted U-type), tower type, half-tower type (improved type), T-type, box type, Γ-type (inverted L-type), U-type and other types according to the mutual arrangement of the combustion chamber and convection flue.

quality product dispute situation:
According to the information provided by the client, the demander and the supplier signed an "EPC General Contracting Contract". The contract stipulates that the project content includes: XX special yellow phosphorus exhaust boiler + 24.5MW extraction condensing steam turbine generator unit project and the survey and design of related supporting systems, equipment procurement, civil construction, installation, commissioning, turnkey project. Due to actual demand, the supply and demand parties signed a "Supplementary Agreement" and agreed to adjust the power station installation plan. The specific adjustment is: XX yellow phosphorus tail gas boiler + 14.5MW extraction condensing steam turbine. The "Report on the XX Yellow Phosphorus Tail Gas Power Generation Project" issued by the
supplier stated that "95% of the waste heat boilers have arrived as a whole." However, the buyer had doubts about whether the arriving boiler was a boiler specially designed for yellow phosphorus exhaust gas, so he applied for an appraisal of whether the "boiler" involved in the case was a special boiler for yellow phosphorus exhaust gas.
quality analysis results:
The appraisal expert group discussed and comprehensively analyzed the relevant information, on-site investigation and test data of the "boiler" involved in the case, and made the following appraisal opinion:
Based on the existing information and the existing status of the "boiler" involved, it cannot be determined that the "boiler" involved in the case is a special boiler for yellow phosphorus exhaust gas.
