　　There are two basic operation modes of biomass hot blast stove: interlocking automatic and interlocking semi-automatic.

　　(1) The interlocking automatic operation is to change the state of the biomass hot blast stove according to the preset air supply mode and time, and the entire furnace changing process is fully automatic control.

　　(2) The interlocking semi-automatic operation refers to the state conversion of the hot blast stove under the command of the operator according to the pre-selected air supply mode. The entire furnace changing process is controlled by semi-manual and semi-automatic. The interlock is to protect the equipment so as not to delay the work. It is necessary to ensure that the hot blast stove can be continuously sent to the blast furnace during operation to avoid accidents. Therefore, during the furnace replacement process, there must be one or more hot blast stoves to supply air to the blast furnace. , and other excess hot blast stoves can be converted into burning or other states.
