Spreader Stokers
Indeck Keystone Energy designed and produced hundreds of spreader stokers for a variety of solid fuel applications for over fifty years.
Both the Travagrate® front ash discharge traveling spreader stoker and the water cooled stationary grate spreader stoker are utilized to produce steaming rates from 25,000 pounds of steam per hour (11.3 Metric tons) up to 500,000 pounds of steam per hour (227 Metric Tons) firing a wide variety of solid fuels.
Depending on stoker type, potential fuels can include:
- Coal and Lignite
- Wood and Bark
- Bagasse
- Demolition Wood
- Tires (Shredded)
- RDF (Processed Urban Garbage)
- Agricultural Wastes (Stalks, Shells, Fronts, Etc.)
As one of the original technologies developed for firing solid fuels, spreader stokers provide a vital means of producing steam using an efficient and reasonably priced machine.
Stokers can be designed in a multitude of widths and lengths to custom-fit the shape and other physical constraints of any steam generator.
In addition to the traditional coal or lignite fired applications, both the Indeck Keystone Energy Travagrate® and stationary grate stokers have been supplied to fire the less common biomass fuels found throughout the U.S. and the world.
A brief list of projects includes:
- U.S.A. (Wood, Tires, RDF)
- Columbia (Bagasse)
- Canada (Wood)
- Ethiopia (Bagasse)
- Denmark (Wood, Coal)
- Philippines (Bagasse)
- India (Bagasse and Lignite)
- Ireland (Wood)
Indeck Keystone Energy provides service, repair, and upgrades for all stokers.
IKE under the former boiler company names of; “Erie City Iron works”, “Zurn Energy”, “Aalborg Industries”, and “Erie Power Technologies”, has designed and produced hundreds of spreader stokers for a variety of solid fuel applications for over
fifty years.
Both the Travagrate front ash discharge traveling spreader stoker and the water cooled stationary grate spreader stoker have been utilized to produce steaming rates from 25,000 pounds of steam per hour up to 500,000 pounds of steam per hour.
Depending on the type of stoker, the fuels able to be fired include;
- Coal and Lignite
- Wood and Bark

In addition to the traditional coal or lignite fired applications, both the IKE traveling grate and stationary grate stokers have been supplied to fire the less common biomass fuels found throughout the world.
A brief list of prior international projects includes;
- Columbia – Bagasse
- Canada – Wood
- Ethiopia – Bagasse
- Denmark – Wood
- Philippines – Bagasse
- India – Bagasse and Lignite
- U.S.A. – Wood, Tires, RDF
- Ireland – Wood
Along with the ability to produce a variety of stoker equipment specifically designed for each installation, IKE has the staff and
skills needed to provide equipment properly documented and transported anywhere in the world.
Offering on-line availabilities greater than 98% and reinjection systems able to reduce combustible losses below 2%, a spreader stoker can provide decades of dependable service with a minimum of maintenance.
Traveling or stationary grate stokers provide ease of maintenance and problem free operation.
