Problems solved by technology

Although continuous and uninterrupted fuel addition can be achieved, there are still some deficiencies in the control of the fuel level of the combustion furnace, and the relationship between the material level and the feed cannot be effectively controlled.
This shows that the prior art scheme is also difficult to meet people's actual needs

Embodiment 1

[0025] It includes a detection signal transmitting device, a detection signal receiving device and a feeding control device. A detection signal transmission device and a detection signal receiving device are arranged on both sides of the furnace 6. The detection signal transmission port and the detection signal receiving port are located in the two sides of the furnace 6. Corresponding to the side level, the horizontal emission line of the detection signal emission port is the positioning position of the charge burning.

[0026] The detection signal transmitter head 1 of the detection signal transmitter device is connected to the detection signal transmitter head support 3, the detection signal transmitter head support 3 is connected to the furnace 6, and one end of the detection signal transmitter head support 3 outside the furnace 6 is for transmitter The other end is the detection signal transmitting port 13 in the furnace 6; the furnace 6 is connected with the feed pipe 7. Th...

Abstract

The invention relates to a burning furnace burden level control design method, a control device and a control method. The design method comprises the following steps of: designing a settled position and a relative position for burning furnace burden according to the sizes of a hearth and a furnace mouth or by combining burning firepower; stopping a feeding device from feeding by using a feeding control device when the position of the furnace burden in the hearth is higher than the settled position; and starting the feeding device to feed by using the feeding control device when the position of the furnace burden in the hearth is lower than the settled position, wherein the position of the furnace burden after the feeding device is started each time is higher than the settled position; the position which is higher than the settled position is the relative position for burning the furnace burden; and in a stable burning interval, the furnace burden is burnt between the settled position and the relative position. The feeding process is controlled by using the settled position of the burden level of a fuel in the hearth; and through reciprocating work, the position of the fuel in the hearth is stabilized, sustained burning is realized, and a persistent long-term fire demand is met.

Description

Technical field [0001] The invention belongs to a solid fuel domestic furnace or stove, and relates to a combustion furnace material level control design method, a control device, and a control method of a combustion furnace with full-automatic fuel feeding from top to bottom combustion. Background technique [0002] The combustion device that uses the top-down combustion method for fuel has undergone continuous development. The existing feeding device such as "Closed Biomass Fuel Feeding Device", patent number: CN200820185125.6, the upper end of the spiral device is provided with the spiral The flap door device of the device, the flap door device is provided with a fuel inlet, the lower end of the screw device is connected to a metering silo, and the metering silo is equipped with a fuel level detection device; another example is the applicant "A fully automatic combustion furnace and furnace fuel feeding device" CN201110072JS3.7, which adopts mobile replenishment and push-type ...
