Industrial Watertube Boilers

The Industrial Watertube Boilers business unit supplies new boilers and combustion equipment to a variety of industries. Service is provided incorporating capacity and efficiency improvements to older boilers, repairs and maintenance, supply of original equipment manufacture (OEM) spares, reliability studies and metallurgical services.

The range of new boilers includes:

  • Coal-fired boilers with traveling grate and CAD spreader stokers
  • Fibrous Fuel-fired boilers with CAD spreader stokers as well as pinhole and dump grates
  • Oil-fired / gas-fired boilers

Our customer list covers the widest range of major industries throughout sub-Saharan Africa including: sugar, food and beverage, chemical, petrochemical, steel, metallurgical, pulp and paper, textiles and many others. As a world-class internationally competitive operation we have been contracted by the World Bank, under the auspices of the Global Environmental Facility, as a technology transfer source to assist Chinese boiler manufacturers burning low-grade high-ash Chinese coals to reduce emission levels to acceptable international standards. A 75-tons-per-hour JOHN THOMPSON coal-fired watertube boiler incorporating the high-efficiency zoned CAD stoker was manufactured at the Jinan Boiler Works outside Beijing as a verification unit prior to general manufacture in China.

Our teams are available at short notice for routine or emergency procedures. Refurbishment, retrofitting, shutdowns, service contracts, relocation and re-builds are carried out on all types of boilers, furnaces and mechanical plant and associated equipment. Our service covers more than 100 John Thompson watertube boilers, 90 utility boilers in Eskom and municipalities, and over 700 pressure vessels. 

We offer boiler modeling capability, using various tools such as CFD, circulation modeling and other techniques, unparalleled in the industrial markets serviced by us. This enables us to get the maximum utilization from existing watertube boilers of all types and size irrespective of the OEM. Examples of this would be capacity and / or efficiency upgrades for existing plant.
