Problems solved by technology

Due to the influence of flame radiation in the furnace and flue gas flow rate, flow rate changes and other factors, this index cannot be directly detected, and can only be calculated according to the boiler load through the thermodynamic formula. The entire calculation process is complicated, and there are too many related data. lead to poor data accuracy

Abstract

The invention discloses a detecting method for the smoke gas index 850 DEG C / 2S design requirement of a solid incinerator. Through the lowering speed of the temperature of a first flue, the temperature of a secondary air spray-in opening, the average temperature of the first flue, the primary air flow rate at the average temperature of the first flue and the ascending height of the smoke gas in two seconds are sequentially obtained according to formulas, and finally, the exhaust temperature of the smoke gas after the two seconds is obtained, so whether the exhaust temperature is higher than 850 DEG C or not is judged, and whether the design requirement of a smoke gas index is met or not is further judged. Therefore the detection method provided by the invention has the advantages that the simplicity and reliability are realized; the calculation process is greatly simplified; and the accuracy and the reliability of the 850 DEG C / 2S data detection are improved.

Description

technical field [0001] The invention relates to a detection method, in particular to a detection method for the design requirements of the flue gas index of a solid incinerator. Background technique [0002] In waste incineration, 850°C / 2S is a very important design requirement for flue gas indicators. Specifically, 850°C / 2S means that the temperature of the flue gas discharged during incineration cannot be lower than 850°C, and the temperature of the flue gas in the furnace The residence time is not less than 2S. The design requirements of the flue gas index ensure that the combustibles have sufficient reaction time in the furnace so that they can be burned as much as possible. Due to the influence of flame radiation in the furnace and flue gas flow rate, flow rate changes and other factors, this index cannot be directly detected, and can only be calculated according to the boiler load through the thermodynamic formula. The entire calculation process is complicated, and th...
