Optimizing Steam Boiler Efficiency: Comprehensive Water Treatment by Dantek

Steam boilers are the workhorses of various industries, providing essential heat and energy for countless processes. However, ensuring their optimal performance and longevity requires more than just regular maintenance; it demands a comprehensive water treatment strategy. In this blog, we delve into the intricacies of steam boiler water treatment, highlighting the critical role played by Dantek’s advanced approach based on BS2486 standards.

The Legal Imperative: A Written Scheme of Examination

Under regulation 8 of the pressure systems safety regulations, a written scheme of examination is a legal requirement. This scheme outlines safe operating limits, pressures, temperatures, and other essential factors. Neglecting these aspects can lead to boiler breakdowns or, in worst-case scenarios, catastrophic failures. To ensure compliance and safety, reference HSE Document INDG436 for industry guidance and best practices.

Health and Safety Considerations

Beyond legal obligations, various health and safety considerations demand attention in steam boiler management. These include CoSHH issues, explosion and fire risks, scalding hazards, manual handling protocols, fall prevention measures, annual inspections, establishment of safe operating parameters, and ensuring the training and competence of staff. A comprehensive risk assessment, detailing control measures and procedures, should be regularly updated to adapt to changes and advancements.

Understanding Boiler Ratings and Basic Steam Processes

Steam boiler efficiency starts with a clear understanding of boiler ratings and the basic steam process. Boiler outputs are rated based on their capacity to provide steam, usually expressed in Ilbs/Hr or Kg/Hr. The “from and at 100 degrees Celsius” notation in boiler ratings signifies that the stated output is achievable when the feed water supplied to the boiler is at 100 degrees Celsius. Calculating steam output considering feed temperature and operating pressures is crucial for accurate performance assessment.

The basic steam process involves several key components, including the hotwell (a mixture of condensate return and treated water makeup), feed pumps, boiler blowdown (to manage boiler concentration), condensate system (capturing condensed steam), sparge pipe (for heating the hotwell), and chemical dose pumps (to maintain water quality).

Water Treatment

Water treatment lies at the heart of optimizing steam boiler efficiency. Dantek’s approach aligns with BS2486 guidelines, ensuring the best possible performance and extended system lifespan. Corrosion poses a significant threat to boiler integrity. Calcium hardness scale, phosphate scale, and silica scale can impede heat transfer, promote corrosion, and obstruct pipework. The consequences of inadequate water treatment range from reduced plant life and increased maintenance costs to failed insurance inspections.

Here at Dantek our water treatment regimen addresses these challenges comprehensively:

  • Corrosion Control: Through meticulous water treatment, system metals are protected from corrosion.
  • Scale Deposition Prevention : The main factor in the control of scale on steam boilers is the pretreatment, which encompasses design, installation, maintenance, and testing of pretreatment plants. This is further backed up by accurate control of our state-of-the-art chemical scale inhibitors, polymers, and sludge conditioners, ensuring efficient system operation while preventing scale and sludge deposition.
  • Suspended Solids Management: This is controlled by the polymers, sludge conditioners, and by accurate control of alkalinity and chemical concentrations within the boiler, ensuring effective management of suspended solids and safeguarding system functionality.

The Power of Regular Monitoring

Regular analyses of boiler water, feed water, softened supply, and condensate water quality are imperative. Monthly analysis ensures lasting results, maintaining system efficiency and preventing potential issues.
