COAL FIRED BOILER
CONTROL SYSTEMS

Boiler Systems

In 2007, we designed a control system to increase the efficiency of Coal fired Boilers and reduce Coal consumption and a control system that maintains a constant pressure during loading and non loading times. We have installed in excess of a 160 of these systems throughout South Africa and neighbouring countries.

We also:

  • Inspections of Boilers – Mechanical and Electrical
  • Inspections of Condensate Return steam lines
  • Survey and reporting on efficiency
  • Modifications to existing Electrical systems
  • Installation of new Boiler systems onto new or existing Coal Fired or Oil fired Boiler Systems
  • Modifications to Guillotine Doors (Automatic or Chain system conversions)
  • Continuous O2 or CO2 monitoring results in controlled gas emissions
  • Coal consumption and steam to coal ratio

Advantages of a Control System:

  • Boiler capacity, steam pressure is improved and the Production efficiency is increased / enhanced.
  • Fuel savings are achieved up to 22% on mechanically sound installations, and up to 31% on installation where our rectifications were implemented.
  • Variable speed drives yield a savings of 35-45% in absorbed electrical compared consumption to existing damper controlled draught systems.
  • Marked reductions in operating noise levels within the boiler house are achieved.

Savings

  • With the installation of all CAL systems wear, tear and maintenance costs of combustion equipment is reduced.
  • Longer service intervals due to controlled (combustion) thermal inputs.
  • Operation friendly with minimal operator input resulting in less error.
  • Optimal Turn down ratio in excess of 4:1

EXISTING INSTALLATIONS

Our installations throughout Southern Africa include the following industries:

  • Wine
  • Paper Milling
  • Food Additives and Spreads
  • Food Processing
  • Injection Moulding
