Abstract: A production facilities monitoring method monitors an operation status of a plurality of production facilities of a same kind located at a plurality of production sites and includes: a data information preparation step of aggregating operational data of each of the production facilities for each of the production sites; a data accumulation step of accumulating the operational data aggregated at the data information preparation step into a computer located at a data accumulation site; a data analysis step of analyzing a current operation status at each of the production facilities, using current operational data and past operational data accumulated at the data accumulation step; and an operation status determination step of determining whether operation is abnormal at each of the production facilities, based on an analysis result of the data analysis step.

Abstract: An operation method for production facilities operates production facilities of a same kind located at production sites, and includes: a data information preparation step of aggregating operational data of each of the production facilities for each of the production sites; a data accumulation step of accumulating the operational data aggregated at the data information preparation step into a computer located at a data accumulation site; a data analysis step of analyzing an operation status of each of the production facilities, using the operational data accumulated at the data accumulation step; a data display step of displaying information on analyzed the operation status of each of the production facilities on a display unit located at each of the production sites; and a facility operation step of referring to the displayed information and operating a production facility located at a second production site from a first production site.

Abstract: A combustion apparatus has a plurality of longitudinally elongated gas burners, each having a burner port on an upper end thereof. A damper is disposed to cover gas inlet ports on an upstream end of an air-fuel mixing tube portion of each of the gas burners. The damper has formed therein ventilation holes for limiting primary air. The ventilation holes overlap, and are smaller than, the gas inlet ports. The damper has #1 ventilation holes having obstacles against which the fuel gas to be ejected from the gas nozzles strike, and #2 ventilation holes without obstacles. Poor combustion such as flame lifting is restricted and combustion noises are reduced.
