Embodiment 1

[0033] Embodiment 1: Auto-ignition method for biomass pellet fuel with the highest metal content

[0034] For raw materials such as corn stalks and Korean pine that contain relatively high Si elements and other alkali metal elements, the Si content is basically 25%, and the K element content is 10% to 15%. During combustion, the slagging is the most serious, the ash content is the most, and the ignition is the most difficult. . When igniting, the feed amount of biomass particles is 350g, and the power of the resistance rod is set to high-grade, the power is 400W~450W, the power is the largest, and the heat generated is high. 3.5m / s, to ensure that more heat is generated during ignition. At the same time, the wind speed of the centrifugal fan is the highest, providing higher hot air, which is conducive to the ignition of biomass pellet fuel with the highest metal content.

Embodiment 2

[0035] Embodiment 2: Auto-ignition method for biomass pellet fuel with higher metal content

[0036] For raw materials such as wheat straw and rice straw, which contain generally high Si elements and other alkali metal elements, slagging is serious during combustion, and ignition is difficult. When igniting, the feed amount of biomass particles is 300g, and the power of the resistance rod is set to the mid-range, the power is 350W~400W, the power is higher, and the heat generated is higher. s ~ 3.0m / s, to ensure that more heat is generated during ignition. At the same time, the wind speed of the centrifugal fan is higher, providing higher hot air, which is conducive to the ignition of biomass pellet fuel with higher metal content.

Embodiment 3

[0037] Embodiment 3: be used for the auto-ignition method of the general biomass particle fuel of metal content

[0038] Cotton stalks, larch and other raw materials contain low Si and other alkali metal elements, less slagging and less ash after combustion, and easy ignition. When igniting, the feed amount of biomass particles is 250g, the power of the resistance rod is set to a low level, the power is 300-350W, and the power is the minimum. Heat and hot air can ignite biomass pellet fuel with average metal content.

Abstract

The invention discloses an automatic ignition method and an automatic ignition device for biomass particle fuel, which belong to the technical field of renewable energy sources. In the technical scheme, the automatic ignition device comprises a combustion chamber (1), a centrifugal blower (6) and an ignition mechanism (7); hot air is used for ignition in the ignition method, and the centrifugal blower (6) supplies high-temperature hot air to the inside of the combustion chamber (1) through the ignition mechanism (7) so as to heat the biomass particle fuel (2) in the combustion chamber; and in order to shorten ignition time and improve combustion efficiency, the centrifugal blower (6) supplies air to the combustion chamber (1) for three times, and photo-signals are acquired by a photo sensor (8) and fed back to a control system (5) so as to realize automatic ignition. By the automatic ignition method and the automatic ignition device for the biomass particle fuel, the problems of difficulty in ignition, low combustion efficiency and the like of the biomass particle fuel are solved, and support is provided for the combustion technology of the biomass particle fuel.

Description
