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.
Recently, Zhengzhou Fangkuai Boiler Sales Co., Ltd. traveled to Dhaka, the capital of Bangladesh, to attend the Bangladesh International Textile, Knitwear & Garment Industry Exhibition (BTKG 2026). It showcased industrial thermal equipment and system solutions adapted to the whole process of textile printing and dyeing, actively expanding the South Asian market.
Bangladesh is an important global producer and exporter of textiles and garments. As a pillar local industry, the textile sector has long-term and strong demand for high-efficiency, stable and energy-saving industrial boilers and thermal equipment, with broad market potential. This exhibition participation is an important measure for Zhengzhou Fangkuai Boiler Sales Co., Ltd. to advance its internationalization strategy and further explore overseas markets.

Relying on its technological accumulation and manufacturing advantages in the field of thermal energy equipment, the company provides targeted thermal energy solutions for local textile, printing and dyeing, garment manufacturing and other industries, helping enterprises improve production efficiency and reduce operating costs. In the future, Zhengzhou Fangkuai Boiler Sales Co., Ltd. will continue to focus on overseas market demands, continuously optimize its product and service system, facilitate the high-quality development of the global textile industry with professional and reliable products, and steadily enhance the brand’s competitiveness and influence in overseas markets.

Trust stems from quality
At the beginning of the new year, Fangkuai Boiler and a leading domestic new energy company have reached another important cooperation, successfully signing an order for a total of 500 steam tons.
