Air compressor in waste incineration power plant

Air Compressor Selection and Granklin Solution for Waste Incineration Power Plant
the demand for compressed air in waste incineration power plants is special, and it is necessary to take into account the process accuracy, air purity and equipment stability. The following are the core requirements of air compressors in waste incineration power plants and the adaptation advantages of Gelanklin water lubricated single screw air compressors:

core demand for air compressor in 1. waste incineration power plant

1. no oil pollution
   • compressed air may be in direct contact with key equipment in the incineration process (such as bag dust collector and flue gas analyzer) or involved in fly ash transportation. If it contains oil, it will cause filter bag blockage, instrument failure, and even pollute incineration products (such as fly ash), which will affect environmental protection standards.
   • Requirements: The oil content of compressed air for instruments shall be ≤ 0.01 mg/m & sup3;(close to the oil-free standard), and the oil content of power gas shall be ≤ 1 mg/m & sup3;.
2. High purity and cleanliness
   • particulate matter control: instrument gas needs ≤ 0.01μm particles ≤ 2000/m & sup3;(ISO 8573-1 Class 1), power gas needs ≤ 1μm particles ≤ 10000/m & sup3;(Class 2).
   • Moisture control the pressure dew point of instrument gas shall be ≤-40 ℃ (adsorption dryer), and the power gas shall be ≤-20 ℃ (refrigeration dryer) to prevent condensed water from affecting the operation of equipment.
3. Stable air supply and pressure control
   • the waste incineration process needs continuous and stable air pressure support, and the pressure fluctuation may lead to the decrease of the blowback efficiency of the bag filter and the data distortion of the flue gas analyzer.
   • Requirements: Air supply pressure fluctuation ≤ ± 0.05MPa, suitable for 24 hours continuous operation.
4. Environmentally friendly and low maintenance
   • corrosive gases (such as H₂ S and SO₂) may exist in the waste incineration workshop, so it is necessary to reduce the frequency of equipment maintenance to avoid lubricating oil leakage and environmental pollution.

Adaptation Advantages of 2. Grantklin Water Lubricated Single Screw Air Compressor

1. oil-free technical support
   • water-lubricated single-screw technology is adopted to replace lubricating oil with water to eliminate oil pollution from the source. Compressed air naturally meets the strict requirements of waste incineration power plants for oil content ≤ 0.01 mg/m & sup3;, and no additional oil removal equipment is required.
2. High purity and stable gas supply
   • precision filtration: Multi-stage filters (such as 0.01μm precision filters) can be integrated to ensure that particulate matter and moisture meet the standards.
   • Constant pressure: Single screw and star wheel precise coordination, adapt to high load operation, pressure fluctuations, to ensure the stability of the incineration process.
3. Environmental Protection and Cost Advantages
   • no waste oil discharge water lubrication technology avoids lubricant replacement and waste oil treatment, reducing environmental compliance costs.
   • Low maintenance requirements only regular replacement of filter elements and water quality monitoring are required, and maintenance costs are reduced by more than 40% compared with traditional oil-lubricated air compressors.
4. Adapt to harsh environments
   • moisture-proof and corrosion-proof: The water lubrication system is more adaptable to humid and corrosive environments, avoiding the performance degradation of lubricating oil due to moisture condensation, and is suitable for the high humidity and corrosive gas environment of the waste incineration workshop.

Typical Application of 3. Grankering Air Compressor in Waste Incineration Power Plant

1. blow-back of bag filter
   • drive the pulse valve and regularly back-blow the filter bag of the bag filter to remove the attached dust and ensure that the dust removal efficiency is stable at more than 99.9%.
2. Flue gas analyzer blowback
   • provide clean compressed air for the flue gas online monitoring system (CEMS), and blow back the sampling probe to prevent dust blockage and ensure accurate flue gas emission data.
3. fly ash conveying
   • the compressed air is used to transport the fly ash to the ash silo to avoid secondary pollution of the fly ash, and at the same time provide air source for the ash silo gasification plate to prevent the fly ash from being hardened.

4. selection recommendations

waste incineration power plants should be preferred oil-free, high purity, stable gas supply the air compressor. Granklin water-lubricated single screw air compressor is integrated with precision filtration system through oil-free technology design, which can fully meet the stringent requirements of the incineration process for compressed air, while reducing maintenance costs and environmental risks. It is an ideal choice for waste incineration power plants.

Conclusion
the air compressor of waste incineration power plant should have the characteristics of oil-free, high purity and stable gas supply. Granklin water-lubricated single screw air compressor takes oil-free technology as the core, combined with efficient filtration and stable pressure control, to provide reliable and clean compressed air solutions for waste incineration power plants, helping to achieve environmental protection standards and efficient operation goals.
