Quality appraisal of biomass energy prime mover equipment

biomass energy prime mover equipment takes the efficient conversion of biomass and the synergy of energy output as its core principles. By optimizing gasification efficiency, calorific value conversion rate and emission control, it achieves the synergy of stable energy supply of biomass fuel, carbon emission reduction and system continuity. It is widely used in biomass power plants, district heating systems, industrial steam supply and other fields. In cogeneration, it is used for efficient power generation in the biomass gasification combined cycle; in distributed energy, it meets the clean heating needs in rural areas; in carbon capture scenarios, it ensures the energy supply of negative carbon emission technologies. Compared with traditional fossil energy equipment, biomass power equipment has the characteristics of low-carbon cycle, wide fuel adaptability and intelligent control, and is the core equipment of green energy transformation.

Zhongke Testing is a product quality appraisal service organization registered with the court. It can provide quality appraisal services for biomass energy prime mover equipment. It has a professional appraisal team and advanced instruments and equipment to provide fair and accurate appraisal results for the quality appraisal of biomass energy prime mover equipment.

With the strengthening of carbon emission reduction policies, related quality dispute cases have increased significantly. The judicial dispute focuses on:

1. Disputes over performance indicators: gasification efficiency is not up to standard and the calorific value conversion rate is insufficient;

2. Material defects: poor temperature resistance of the gasifier refractory lining and corrosion rate of the heat exchange tube of the waste heat boiler;

3, process issues: fuel pretreatment system screening accuracy deviation, SCR denitrification system ammonia escape rate;

4, contract performance dispute: core modules (such as high-temperature filter material dust collector, carbon capture unit integration) are inconsistent with the technical agreement.

Test items:

The technical method for quality identification of biomass energy motive power equipment includes the following steps:

1. On-site investigation: On-site inspection of equipment operation, collection of fault information and related data.

2. Comprehensive testing: Test equipment performance, energy consumption, environmental protection indicators, etc. according to identification standards.

3. Failure analysis: Conduct failure analysis on the defective parts of the equipment to determine the cause of the defect.

A biomass power plant of the applicant signed a "10MW Gasification Power Generation System Procurement Contract" with an equipment manufacturer of the respondent, agreeing that the gasification efficiency is ≥82%. After being put into production, the actual measurement was only 72%. The manufacturer argued that it was caused by the excessive moisture content of the raw materials.

Identification and analysis results:

The quality analysis expert group discussed and comprehensively analyzed the relevant information, contract technical agreements, on-site inspection case materials and other data on "biomass energy prime mover equipment", and made the following quality analysis opinions:

The biomass energy prime mover equipment involved in the case de The softening point of the gasifier refractory lining is only 1350°C (agreement ≥1450°C), and the heat loss increases by 8%; the screen hole blocking rate of the raw material crushing system is 30% (agreement ≤10%), and the particle size qualification rate is only 75%; the ammonia escape rate of the SCR system is 5ppm (agreement ≤3ppm).

The appraisal conclusion determined that defects in equipment materials and workmanship were the main cause of insufficient energy efficiency.

Biomass energy prime mover equipment quality appraisal report should include:

1, purpose of appraisal (such as attribution of energy efficiency disputes, environmental compliance verification) and reference standards;

2, equipment model involved, process parameters, operation logs;

3, testing methods and equipment list ( Such as gas chromatograph, flue gas analyzer);

4, analysis of detection data and failure correlation (such as the impact of temperature resistance of refractory materials on gasification efficiency);
