Fuel blending combustion evaluation method, system and device

Abstract

The invention discloses a fuel blending combustion evaluation method, system and device. The method comprises steps of acquiring as-fired coal blending combustion information, fuel-related small and micro event information and environmental protection alarm information in the current blending combustion evaluation time period according to the blending combustion evaluation time period; calculatingto obtain a real-time fuel comprehensive consumption difference according to the real-time operation parameters of the SIS system, and calculating to obtain a fuel comprehensive consumption difference mean value in the current blending combustion evaluation time period according to the blending combustion evaluation time period; acquiring as-fired coal blending combustion information, fuel-related small and micro event information and environmental protection alarm information in the current blending combustion evaluation time period according to the blending combustion evaluation time period, and performing data processing to obtain a safety score and an environmental protection score respectively; and judging according to the safety score, the fuel comprehensive consumption difference mean value and the environmental protection score to obtain a blending combustion fuel evaluation conclusion corresponding to the as-fired coal blending combustion information. Whether a fuel blendingcombustion mode, field equipment and an operation mode are suitable for on-line evaluation or not can be achieved, a blending combustion scheme is rapidly corrected, and the labor cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of coal sample blending analysis, and more specifically, relates to a fuel blending evaluation method, and also relates to a fuel blending evaluation system and device. Background technique [0002] With the consolidation of the coal industry, great changes have taken place in the coal market. The supply of the designed coal types of some thermal power plants has been reduced, which cannot support the normal production of the power plants; the prices of the designed coal types of some thermal power plants have risen sharply. Co-combustion of other low-priced coal types; or co-combustion of industrial waste, sludge from urban wastewater treatment, biomass coupling, etc. Fuel co-combustion has become the norm in thermal power plants. How to safely and economically reduce fuel costs has become an important issue for thermal power plants. [0003] At present, the main way to formulate the blending plan ...
