Energy efficiency testing of boiler equipment is a very important and authoritative test for boiler manufacturers and customers using boilers. The test results obtained after the energy efficiency test are powerful indicators for measuring whether the performance indicators of the boiler products of the boiler manufacturer have reached the guaranteed value. In addition, it can also identify the main factors that affect the results of energy efficiency testing, and by analyzing the influencing factors, manufacturers can adjust short-term items to make the product more efficient and safe. The ultimate beneficiary of these adjustments is the customer, because the detection content such as the thermal efficiency of the boiler directly affects the energy consumption of the boiler and is related to the interests of the customer.
So what do boiler energy efficiency tests do? Zhengzhou Fangkuai Boiler Company will give you the answer.
The main contents of the boiler energy efficiency test are as follows.
1. Boiler thermal efficiency test
The main tests are boiler evaporation, boiler excess air coefficient detection, exhaust temperature, fuel combustion efficiency, boiler thermal efficiency test, fuel consumption, and gas-air ratio.
2. Energy efficiency test of new boiler products
Determine whether the various thermal performance indicators of the boiler are consistent with the design and determine the operation mode of the equipment. Such as boiler evaporation, boiler thermal efficiency, combustion efficiency, various heat losses and so on.
3. Boiler operation adjustment test
Determine the most economical mode of operation of the boiler, and identify defects in the operation of the boiler. Such as the maximum boiler load, minimum boiler load, fuel requirements, economic load, reasonable exhaust temperature, optimal air coal ratio, excess air coefficient, secondary air ratio and so on.
4. Contrast test of thermal performance before and after boiler renovation
Test changes in evaporation, effects of combustion, boiler thermal efficiency, and more.
5. Fuel industry analysis, element analysis
Judging the quality of fuels such as coal, oil, and gas is convenient for enterprises to control the quality of fuel entering the plant.
6.Water quality detection and scale sample analysis
Judge the water quality, control the boiler water index, and prevent boiler scaling.
We, Zhengzhou Fangkuai Boiler Co., Ltd. (Fangkuai), are excited to announce our participation in the Indonesia International Heating Technology Exhibition 2025. We will be showcasing our advanced boiler systems engineered for higher efficiency, lower emissions, and sustainable energy performance.
