What water should be used to produce the steam in the boiler?

23 May 2025

The quality of the water used to produce the steam in the boiler will have a profound effect on meeting the objectives such as safe operation, maximum combustion and heat transfer efficiency, minimum maintenance and long working life.

As a result, there is a need for the boiler to operate under the following criteria:

1. Steam Quality and Stability
High steam purity: No contamination by coal ash, soot, or other impurities.
Stable steam output: Constant pressure and temperature to ensure consistent food processing results.
2. Hygiene and Safety
No direct contact: Boiler water, combustion gases, or particulates must not come into contact with food.
Proper water treatment: To prevent scaling, corrosion, and contamination.
Regular cleaning and maintenance: Prevents microbial growth and buildup of residues.
3. Emission Standards
Adherence to environmental regulations: Limits on SO₂, NOₓ, particulate matter, and CO emissions.
Dust collectors and scrubbers: Installation of filtration and scrubbing systems to reduce emissions.
Ash handling: Safe disposal or treatment of coal ash to avoid contamination.
4. Energy Efficiency
High thermal efficiency: To minimize fuel consumption and operational costs.
Heat recovery systems: Use of economizers or air preheaters to improve efficiency.
5. Automation and Control
Automated controls: For fuel feeding, combustion, blowdown, and water supply.
Safety interlocks: To prevent accidents and ensure safe operation.
