Travagrate Stokers. The Travagrate® front ash discharge traveling spreader stoker has been utilized to produce steaming rates from 25000 pounds per hour steam up to 500000 pounds per hour steam. The Travagrate® Stoker has the ability to burn coal lignite wood bark bagasse tires refuse derived fuel and agricultural wastes (stalks shells fronds etc..).
In stoker boilers fuel is either dropped or rammed onto a grate. Stoker boilers are identified by the type of feed mechanism and the type of grate. Feed may be by spreader overfeed or underfeed. Grates may be travelling reciprocating chain or dump type. Approximately 12 stoker boilers are burning TDF supplementally on a commercial basis all in the pulp and paper industry (see Chapter 5).
Spreader stoker Chain-Grate or Traveling-Grate Stoker Boiler Coal is fed onto one end of a moving steel chain grate. As grate moves along the length of the furnace the coal burns before dropping off at the end as ash. We stop corrosion of Wte and biomass boiler tubes.

The two basic types of overfeed stokers are the chain or traveling grate stoker and the water-cooled vibrating grate stoker. Technically a spreader stoker is also a type of overfeed stoker. However because it is commonly considered in a class by itself due to its unique features it will be classified separately in this text. A typical chain grate overfeed stoker is illustrated in Figure 5. It consists of a continuously
Gravity Take-up Catenary Grate A traveling grate must maintain continuous tension in order to run smoothly and avoid jamming of the grate and grate chain. The Travagrate® Stoker maintains this tension by employing the simplest force known in nature gravity. The tension is achieved by having the hang in a natural catenary curve from the s drive shaft to the ...
