Maintenance and Upkeep of Boilers and Fish Meal Processing Chains

Importance of maintenance and upkeep of boilers and fish meal processing chains

Boilers are indispensable equipment in heavy industries such as petrochemicals, metallurgy, food processing, and many others. Operating under high pressure and temperature conditions, boilers are susceptible to wear and tear, even with regular maintenance. The performance and safety of boilers largely depend on regular maintenance and cleaning.

Operating and monitoring procedures for boilers

During operation, operators must adhere to procedures and guidelines from the manufacturer. Keeping records in an operational logbook is critically important. It not only helps to track performance but also detects potential issues.

Maintenance during shutdowns of boilers and fish meal processing chains

When the boiler is idle for an extended period, maintenance cannot be overlooked. For boilers that are inactive for a month or more, dry maintenance methods are applied. For shorter downtimes, wet maintenance is the best choice.

Dry Maintenance Method

Step 1: Drain Water and Open Doors

  • Drain all the water from the boiler.
  • Open the manhole covers on both chambers.
  • Open the valves and remove the inspection covers of the inlet pipes.

Step 2: Interior Cleaning

Clean the inside of the chambers, the tube stacks, and the inlet pipes.

Step 3: Drying

Use a low flame to dry the cleaned parts. Caution: Do not use a high flame.

Step 4: Quicklime Treatment

  • Place 25-30 kg of quicklime, with grain sizes ranging from 10-30 mm, into aluminum trays.
  • Put these trays inside both chambers and close all doors and valves.
  • Check the quicklime every 3 months. If it has deteriorated into powder, replace it.

Wet Maintenance Method

Step 1: Drain Water and Clean

When the boiler is not in operation, drain all the water and clean any scale buildup inside.

Step 2: Fill with Water and Heat Boiler

  • Refill the boiler with water.
  • Heat the boiler until the water temperature reaches 100°C.

Step 3: Vent Air and Increase Pressure

During heating, open the bleed valve or safety valve channel to allow air to escape, preventing pressure buildup in the boiler.

Step 4: Stop Heating and Close Valves

  • Cease the boiler operation.
  • Close the bleed valve or safety valve channel.
