The invention discloses a novel fire grate device, belongs to the technical field of boiler manufacturing and aims to overcome the defects of difficult fire grate check and poor ventilation performance in a coal burning boiler, particularly a small boiler in the prior art. The novel fire grate device mainly comprises a fixed fire grate bracket which is provided with a fixed fire grate and two or more power crankshafts; the fixed fire grate consists of fire grate units and is arranged and fixed through a fixed fire grate fixing shaft; the fixed fire grate fixing shaft is arranged on the fixed fire grate bracket; the fire grate unit is provided with a first shaft hole, a second shaft hole and a third shaft hole; the novel fire grate device is provided with a movable fire grate bracket; the movable fire grate bracket is provided with a movable fire grate and a fixed fire grate fixing shaft opening; the movable fire grate also consists of fire grate units and is arranged and fixed through the fire grate fixing shaft; and the movable fire grate bracket is arranged on a power crankshaft through a bearing seat and a bearing. The novel fire grate device is applicable for large, medium and small boilers.
Description
technical field [0001] The invention relates to a component of a coal-fired boiler, which belongs to the technical field of boiler manufacture, and in particular relates to a novel fire grate device used on the boiler. Background technique [0002] At present, the combustion equipment of coal-fired boilers, especially small vertical or horizontal boilers, generally use fixed grates. This type of grate requires operators to perform work such as poking fire, stabbing fire and removing slag in the face of high temperature. The working conditions of personnel are difficult and labor-intensive, and it is difficult to poke into the furnace. It is easy to clean during inspection, and ventilation is often blocked, which affects the normal combustion of fuel and the thermal efficiency of the boiler, resulting in energy waste and environmental pollution. Large and medium-sized boilers with step-by-step and movable grates also have the problems of large ventilation resistance and diffi...
