The valley power utilization rate detection of boilers and kilns is an important means to evaluate their energy utilization efficiency and economic benefits during the off-peak electricity price period. The following are some common methods for detecting the valley power utilization rate of boilers and kilns:

1. Boiler Valley power utilization rate detection method
Data collection:
Collect the operation data of the boiler during the off-peak electricity price period, including input power, output heat, operating time, etc.
Record the load changes, fuel consumption, and other parameters of the boiler during this period.
Energy efficiency calculation:
Calculate the thermal efficiency of the boiler during the off-peak electricity price period using the positive balance method or the reverse balance method.
The positive balance method calculates the thermal efficiency by measuring the input heat and output heat of the boiler; the reverse balance method calculates the thermal efficiency by measuring the various heat losses of the boiler.
Valley power utilization rate evaluation:
According to the operation data of the boiler during the off-peak electricity price period, calculate the proportion of its electricity consumption to the total electricity consumption.
Combining the thermal efficiency and electricity consumption ratio of the boiler, evaluate the valley power utilization rate of the boiler.
Comparative analysis:
Compare the valley electricity utilization rate of the boiler during the valley electricity price period with other periods, and analyze the reasons for the difference.
Based on the comparison results, propose improvement measures to improve the valley electricity utilization rate of the boiler.
2. Valley electricity utilization rate detection method of kiln
Energy consumption monitoring:
Install energy consumption monitoring equipment on the kiln to record the electricity consumption of the kiln during the valley electricity price period in real-time.
At the same time, monitor the production data of the kiln, such as output, quality, etc.
Energy efficiency analysis:
Calculate the unit product energy consumption of the kiln based on the kiln's electricity consumption and production data.
Analyze the energy efficiency level of the kiln during the valley electricity price period, and find out the links and reasons for high energy consumption.
Valley electricity utilization rate calculation:
Calculate the proportion of electricity consumption of the kiln during the valley electricity price period to the total electricity consumption.
Combined with the unit product energy consumption and electricity consumption ratio of the kiln, evaluate the valley electricity utilization rate of the kiln.
Optimization suggestions:
Based on the results of the kiln's energy efficiency analysis and valley electricity utilization rate evaluation, put forward optimization suggestions to improve the valley electricity utilization rate of the kiln.
Optimization suggestions may include improving production processes, improving equipment efficiency, optimizing electricity use, etc.
Notes
When conducting valley power utilization rate detection of boilers and kilns, the accuracy and completeness of the data should be ensured.
The detection methods and evaluation standards should comply with the requirements of relevant national or industry standards.
The improvement measures proposed based on the test results should be fully demonstrated and experimentally verified to ensure their effectiveness and feasibility.
In summary, the valley power utilization rate detection of boilers and kilns is a complex and meticulous process that requires comprehensive consideration of multiple factors. Through scientific detection methods and evaluation standards, the valley power utilization rate of boilers and kilns can be accurately evaluated, and effective improvement measures can be proposed to improve their energy efficiency level.
