Saxlund has developed a new grat where the grate movement is adjusted to current effect output.
The grate has following major advantages: - The new patented grate bars may be rotated to double their service life. - Grate side cooling prevents slag formation which means less maintenance. - The grate bars are machined to tight tolerances and then bolted together to give a uniform air flow over the entire grate resulting in better combustion and no hot spots. - Stable combustion can be achieved even at very low outputs. - The grate design is modular; it can be retrofitted easily into existing boilers or furnaces - All actuators are placed at the front of the grate. This means that there is no maximum width limitation. - When combined with the patented fuel feed system, the whole grate is only used for combustion, not feeding fuel. This means the heat release is maximized.
