Abstract

The invention discloses a virtual detection method for the fuel heat conversion rate of a kiln, which comprises the following steps of: establishing a virtual detection instrument digital model on thebasis of a computer system and system software; a virtual detection instrument measurement mechanism digital model of the fuel heat conversion rate, namely a mathematical model of the fuel heat conversion rate eta, is equal to the ratio of heat energy Qr generated by combustion of fuel entering a furnace to total heat energy QZ of the fuel entering the furnace, and the expression of the mathematical model is as follows: (shown in the description); the technical effect and advantages of the method are that the fuel combustion heat conversion rate is detected, and the indicating value of the fuel combustion heat conversion rate less than 1, namely the heat loss rate of fuel combustion, the fuel loss amount and the fuel loss value correspond to the heat loss rate, and the fuel loss amount and the economic loss (value) are the fuel loss amount at any time or in any time period. Optimized operation and enhanced management are achieved. The purposes of reducing fuel consumption, reducing cost and improving benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of fuel thermal conversion rate research, and more specifically relates to a virtual detection method for fuel thermal conversion rate of a kiln. Background technique [0002] Fuel thermal conversion rate, that is, the percentage of chemical energy converted into heat energy in fuel. This variable plays an important guiding role in the furnace fuel thermal conversion (combustion) process, and is an important link in furnace energy saving and emission reduction. The country's annual kiln fuel consumption is equivalent to billions of tons of standard coal. With the detection data of fuel thermal conversion rate, the best thermal conversion rate management and control can be realized, and the country can reduce the fuel consumption of hundreds of millions of tons of standard coal every year. However, there is no direct detection instrument for the thermal conversion rate of fuel at present. It can be seen th...
