Biomass straw pellet burner

Abstract

The invention provides a biomass straw pellet combustor which can not only combust wood biomass pellet fuels under a controllable state, but also can combust straw biomass pellet fuels under a controllable state. The biomass straw pellet combustor comprises a furnace arch, wherein the right end of the furnace arch is fixedly connected with a combustor feed box, the left end of the furnace arch isfixedly connected with an ash box, a drying box is fixedly connected with the combustor feed box, the upper end of the drying box is connected with a feed inlet, the upper surface of the combustor feed box is connected with an air inlet hole, the back surface of the combustor feed box is provided with an ignition hole, the upper part at the front surface of the furnace arch is provided with a fire-watching hole, the lower part of the furnace arch is designed with an ash removal door, the inner surfaces of the front and back of the inner shell of the furnace arch are connected with radiant panels, the upper part of the inner shell of the furnace arch is provided with a secondary air hole, the lower surface of the outer shell of the furnace arch is fixedly connected with a pulley, the lowersurface of the outer shell of the furnace arch is also fixedly connected with a pulley and an air chamber partition plate, the inner shell of the furnace arch and the lower part of the combustor feedbox are designed with reciprocating static grates, the right end of the connecting rod of each grate is connected with a grate speed reduction motor with an adjustment wheel, and the upper surface ofthe furnace arch is provided with a fire-accumulated hole.

Description

technical field [0001] The invention relates to a burner, in particular to a biomass straw particle burner. Background technique [0002] The currently used burner is a spiral bottom feeding burner, and its feeding method is to enter the combustion chamber from bottom to top, ignite from above and burn from top to bottom, forming a slag layer, an oxide layer, a dry distillation layer, a preheating layer and a new one. material layer. It has the advantages of full combustion, energy saving, no black smoke, small size and easy operation. When the burner burns wood-based biomass pellet fuel alone, because wood pellets have the characteristics of high calorific value, low ash content, high ash melting point, and are not easy to slagging after combustion, the degree of ash accumulation and slagging is low, and the burner can operate normally. However, the biomass pellet fuel based on crop straws has high ash content, low ash melting point, and high alkali metal content in the s...

AI Technical Summary

Problems solved by technology

The test shows that the bottom-feeding burner is not suitable for straw biomass pellet fuel in my country. The above biomass pellet burner can effectively burn woody biomass pellet fuel, but the utilization of straw biomass pellet fuel There are still deficiencies in the field, it is difficult to solve the technical problem of slagging of straw-based biomass pellet fuels, and it is impossible to burn straw-based biomass pellet fuels under controllable conditions
