3 Industrial boiler maintenance energy-saving monitoring items
3.1 Monitoring and inspection objectives
3.1. Energy-saving monitoring of industrial boilers should examine thermal efficiency. 3.1.2 The test of thermal efficiency shall comply with the following provisions: The test of thermal efficiency shall be carried out in accordance with B/11018: The thermal efficiency data provided by the enterprise shall be based on the test report (record A) of the professional unit.
b, thermal efficiency test shall be carried out under the following conditions: After the industrial boiler is newly installed and overhauled, and after technical transformation, the thermal efficiency test time shall not exceed one year: 3.2 Monitoring test items
3.2.1 Smoke mixing degree
3-2.2 Smoke gas coefficient.
3.2.3 Carbon content of furnace materials:
3.2.4 Furnace body surface temperature.
4 Industrial boiler energy-saving monitoring method
4.1 Steel monitoring test sound is carried out under the actual operating conditions of normal production. 4.? Parting time: Start from the thermal condition reaching the set state, and the monitoring time should be no less than 1h. Except for the test day that needs to be analyzed, the readings shall be recorded once every 15 minutes and the average value shall be calculated. 4.3 The instrument of the monitoring station shall be able to meet the requirements of the two-distance salt measurement items. The instrument must be in good condition and within the calibration period. Its accuracy shall not be lower than GB/T 15317-94 approved by the State Bureau of Technical Supervision on December 17, 1994 and October 01, 1995. The test point of the exhaust source shall be carried out on the flue within 1m behind the last stage of the tail heating surface of the industrial furnace. The metering thermocouple shall be placed in the flue to ensure the sealing of the flue. 4.5 Air coefficient
The air sampling should be at the center of the flue within the highest and lowest tail heating surface of the industrial boiler. The air sampling and temperature measurement should be carried out simultaneously:
The air coefficient is calculated according to formula (1):
O, 0.5C0. 2CI
27 - 79 TGG (RO + 0. +TO+ H, + CH,1
Wherein, RO, CO.CH, H.- are the percentage contents of combustion products. For gas and filter fuels, H, and CH are not analyzed. 4.5
For furnaces equipped with mechanical ash removal equipment, samples can be taken regularly at the fire outlet (usually once every 15 to 2 minutes). Pay attention to the uniformity and representativeness of the samples:
The initial number of samples should not be less than 3% of the total amount collected. When the coal content is greater than or equal to the amount collected, the number of original samples should not be less than 10% of the total amount collected. But the total ash quantity is less than 20kg. When the total ash quantity is less than 20g, all samples should be taken. The number of samples after the reduction should be no less than 2kg-1kg. After 1k sealing, check, 4.7 The arrangement of the outer surface temperature of the outer protective body should have representative life, "0.3--] m measuring points should be averaged and the furnace door should be burned. The hole should be probed, etc. should not be arranged within the range of 30nm. 5 Industrial boiler energy-saving monitoring qualified indicators

5-E For Haikong 2 00 m In industrial areas, the qualified indicators of energy conservation monitoring can be adjusted by local energy conservation departments according to the actual situation. 6 Evaluation of industrial furnace energy conservation monitoring results 6.1 The qualified indicators and test items of industrial furnace energy conservation inspection items stipulated in this standard are the lower standards for qualified monitoring. The test items should be used to evaluate the unqualified and qualified ones. Only when all the monitoring indicators are qualified can they be regarded as "energy conservation qualified industrial screening". 6.2 For those who are unqualified, the monitoring unit should make a report on the degree of energy conservation and put forward improvement suggestions. :
The monitoring unit of the energy conservation business furnace
Thermal induced heat
Emission degree
Broad-gas coefficient
The carbon content of the furnace
The outer surface quality of the protective film
