4 Monitoring method for energy saving of flame heating furnace
4.1 Monitoring should be carried out when the flame heating furnace is in actual production. 4.2 During monitoring, the reverse flame heating furnace starts from the time when the thermal condition reaches a stable state, and the monitoring time is not less than 2h; the monitoring time of the conventional flame heating furnace is one heating cycle. Except for the test items that require laboratory analysis, the readings are recorded once every 35 to 20 minutes, and the average value is calculated. 4.3 The instrument used for monitoring should be able to meet the requirements of the monitoring items. The instrument must be in good condition, and its accuracy should not be lower than Class 2.0 within the calibration period.
4.4 Exhaust efficiency
The measurement points of the exhaust gas temperature should be arranged on the flue surface where the flue gas temperature is relatively uniform. According to the size of the furnace, the gas sampling point can be arranged on the flue of the exhaust gas outlet 1-2Ⅱ of the protection body. For flame heating furnaces equipped with waste heat recovery devices, the measuring point can be located at the flue gas outlet of the waste heat recovery device (.5m). The temperature probe seat is lowered to the center of the flue section: 4.5 Basin air coefficient 4.5.1 The air sampling point should be arranged with the exhaust temperature measuring point. The main air sampling and temperature measurement should be synchronized in the flue section. 4.5.2 The air coefficient is calculated by the following formula: O,-0.GCO - C. GH—2CH, 2179 1cG -(RG,10, - CO- H. I For the analysis of the quality of fuel products, H, O, R, O, TO, CH, and CH are analyzed for solid fuels and liquid fuels. 4.6 Checking the carbon content in furnaces (using refining furnaces) 4.6.1 Attention should be paid to the overall uniformity and representativeness of the sample when sampling the value of the propellant. The sampling and shrinking method of ash cleaning can be carried out in accordance with GB/T1)180A (Supplementary Material B212). 4.5.2 The number of original or slag samples should not be less than 2% of the total ash content. When the ash content of the sample is 40%, the number of initial ash samples should not be less than 1% of the total ash content, but the total number should not be less than 30. When the total amount is less than 20g, all samples should be taken. The number of slag samples should not be less than 2kg, 1kg for follow-up inspection and 1kg for storage. 4.7 Surface temperature
4.7.1 The layout of the temperature points in the furnace room should be representative. Generally, they should be evenly arranged according to the temperature zone in the furnace, depending on the surface of the furnace. Size. Generally 0.5--2m". The maximum value of the measured furnace outer surface seam is taken as the benefit test conclusion 4.7.2 The migration of training points should avoid the influence of high temperature over-radiation and latent gas. The visual hole, furnace door, burner hole, hot faucet, upper flue and waste heat device should not be strictly within 0cm (except for special circumstances). 4.8 Unit consumptionwww.bzxz.net
4.8.1 The unit product fuel consumption calculated by the mass of qualified additional workpieces of not less than one production cycle is called comparable unit fuel consumption, newly called comparable unit consumption
4.8.2 The test items of comparable unit fuel consumption have been calculated in accordance with the energy consumption classification standards of the industry. The sampling and testing of fuel shall be carried out in accordance with G2/T 212GB/T10180.
