Problems solved by technology
That is to say, at present, there are only instruments and equipment that can independently detect the ignition point of waste or the burning rate of waste, which need to be tested separately, and the detection efficiency is low; and after the equipment for detecting ignition point analyzes a sample, it is necessary to wait for the detection unit to cool down before proceeding. Test of the second sample

Embodiment Construction
[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0033] Such as figure 1 Shown, a kind of ignition point of the present invention and the method for high-temperature combustion rate integral analysis, it comprises:
[0034] Step S1: setting up two independent high-temperature cavities on the furnace body;
[0035] Step S2: sending the sample into one of the high-temperature chambers;
[0036] Step S3: heating up at a predetermined heating rate until it is detected that the sample just starts to ignite, and record the ignition temperature point of the sample as the ignition point of the sample;
[0037] Step S4: Raise to the target temperature at another predetermined heating rate; record the weight change of the sample corresponding to time and temperature during the whole process in real time, and obtain the atmosphere corresponding to the sample at high temperature through the r...

The invention discloses an integrated analysis method and an analyzer for a burning point and a high-temperature combustion rate, and the method comprises the following steps of S1: setting two independent high-temperature chambers on a furnace body; S2: sending a sample into one of the high-temperature chambers; S3: raising the temperature at a predetermined designed heating rate until the sampleis detected to be ignited, and recording the ignition temperature point of the sample as the ignition point of the sample; S4: raising the temperature to the target temperature at another predetermined designed heating rate to obtain the burning rate of the sample in the atmosphere corresponding to the high temperature; S5: sending out the completed sample, sending the next sample to another coldhigh-temperature chamber, repeating S3 and S4 to complete the detection process; and S6: carrying out continuous injection by switching the two independent high-temperature chambers until the detection of all samples is completed. The analyzer is designed according to the method described above. The invention has the advantages such as simple and compact structure, high degree of automation and greatly improved detection rate.
Description
technical field [0001] The invention mainly relates to the technical field of automatic detection of combustibles, in particular to an integrated analysis method of ignition point and high-temperature combustion rate and an analyzer. Background technique [0002] At present, in the process of solid / hazardous waste disposal, ignition point and combustion rate are very important indicators. The two indicators need to be tested with two different equipment, which is relatively inefficient. The ignition point is the temperature point at which the sample starts to burn in the air; the high-temperature burning rate is the ashing speed of the sample under given atmospheric conditions and high temperature conditions. [0003] For example, in the domestic large-scale coal-fired power plants or biomass power plants and other incineration processes, the incineration fuel is relatively single, and the demand for testing the ignition point of the incinerated products is very small, and o...
