Two UNI 10389-2 and UNI 11859-1 standards for biomass plants
The UNI 10389-2 standard for the analysis of combustion, draft and combustible humidity was published in April 2022 and this offers new perspectives to the market, because it is finally possible to distinguish clean combustion plants from polluting plants on which intervene with the necessary corrections or with the replacement.
The dust analysis has not yet been included, therefore installers and maintenance technicians of thermal power plants will still have to carry out the dust checks according to their own experiences, the manufacturers' instructions or rely on chemical laboratories.
The UNI 11859-1 standard indicates to the installer and maintenance technician the methods for checking existing flue systems, equal to UNI 10845 for gas.

Checks before installation UNI 11859-1
Before installation, the installer must ascertain the suitability of the chimney, for example by using the new UNI 11859-1 standard:
• Check for the presence of any ventilation opening free from obstructions
• General check of the chimney:
• Verification of the leak test certified by the chimney installer
• Verification of the safety distance certified by the installer of the fireplace
• Visual check: • Materials used and compatibility with the installation room
• Criteria for laying the smoke duct, chimney and any manifold
• Chimney pots and outlet quotas
• Internal and external state of conservation (e.g. by video inspection with UNI 10847 compliant rotary head camera)
With fireplaces without assessments, certifications and fireplace plates, the installer will certify them.
Single 230 - Three-phase 230/380
After installing the generator and at each maintenance, the combustion of the generator must be checked and fine-tuned so as not to pollute and checks on manually loaded domestic generators such as fireplaces, stoves or wood inserts include:
• Check the quality of the wood with type, weight, size in compliance with the manufacturer's instructions
• Water content of fuel UNI 10389-2 compliant
• UNI 10389-2 draft measurement • Fume temperature measurement
• Check for an adequate flow of combustion air, eg. through the 4-Pa-test
• UNI 11859-1 smoke regurgitation check
• UNI 11859-1 coaxial exhaust seal check
