Ash removal device and method for combustion disk surface of direct-fired biomass pellet burner

Abstract

The invention relates to a device and a method for removing dust on a combustion disk of a direct-combustion type biomass particle combustor. The device comprises an intermittent transmission mechanism, horizontal arms and vertical arms, wherein the intermittent transmission mechanism is combined with the spindle; the horizontal arms are fixed with the intermittent transmission mechanism; the vertical arms are connected to the two ends of the horizontal arms and are bent downwards; the intermittent transmission mechanism consists of an incomplete gear, an incomplete inner gear disk and a gear disk cushion cover; the incomplete inner gear disk is in sliding fit with the spindle through a shaft sleeve of a disk rack; and the spindle serves as a rotating shaft. According to the position of ash, an adjustable scraper blade is fastened to the two horizontal arms through screws, residual ash of the combustion disk is discharged by the adjustable scraper blade, the ash is discharged by the original ash discharging structure in an ash chamber, the problem that an ash outlet is easily blocked by ash of the existing ash discharging system is solved, cold air is stopped from entering a combustion cavity, the ash is beaten and ground so that the smashed ash is obtained and can be secondarily used conveniently, the ash discharging amount can be controlled by intermittent rotation of the adjustable scraper blade, and afterheat of the ash is recycled as much as possible.

Description

Technical field [0001] The invention relates to an energy-saving burner, in particular to a burning disc surface ash removal device and method of a direct-fired biomass particle burner. Background technique [0002] Biomass pellet burner is a burning appliance that uses high-density pellets made of plant straws and weeds as fuel. The direct-fired biomass pellet burner is a type of biomass burner. [0003] The structure of a biomass burner usually includes a shell, a feeding system, a combustion system, an air supply system, and an ash output system. The combustion system includes a combustion system with different structures. The direct-fired biomass pellet burner uses a basin-shaped combustion plate. The working process of the combustion system is: first, the fuel is sent to the center of the combustion plate through the feeding system for pre-combustion and heating, and then the fuel is sent to the outer plate of the combustion plate by the feeding part to continue burning, and t...

AI Technical Summary

Problems solved by technology

Use a mechanical device to remove the remaining ash on the combustion disk surface, avoid the remaining ash from blocking the air holes of the combustion disk, and reduce the influence of natural wind or artificial ventilation on the side blowing of the combustion disk surface on the furnace temperature. At present, there is no technology for the application of related devices in this industry Appeared, and there was no relevant report in the literature
