Solid fuel furnace automatic controlling method for solid fuel e.g. saw dust, combustion device, involves continuously supplying fuel by using supply device, and controlling speed and/or on-time of supply device based on control factor

摘要

#CMT# #/CMT# The method involves continuously supplying fuel (30) from a storage vessel (16) to a solid fuel furnace (12) in a combustion device (10) by using a supply device (14). The speed and/or on-time of the supply device is controlled by a control unit based on a control factor, where the control factor is energy unit of the supplied fuel, and is calculated by weight and calorific value of the supplied fuel or fuel mixture and determined by weighing defined volume of the fuel by using a measuring device in the supply device. #CMT# : #/CMT# An independent claim is also included for a solid fuel furnace automatic control device comprising a measuring device. #CMT#USE : #/CMT# Method for automatically controlling a solid fuel furnace in a combustion device for solid fuel using a solid fuel furnace automatic control device (claimed). Uses include but are not limited to saw dust, wood chip, wood shaving and pellet. #CMT#ADVANTAGE : #/CMT# The method automatically controls the solid fuel furnace in a stable, flexible and user-friendly manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a combustion device for solid fuels. 10 : Combustion device 12 : Solid fuel furnace 14 : Supply device 16 : Storage vessel 30 : Fuel.
