Do you know how many tons of boiler you should buy? Do you understand boiler control systems? Here are 10 key points for boiler selection to help you decide.

First, let's take a look at the two calorific values ​​of fuel: high calorific value and low calorific value. High calorific value refers to all the heat released when the fuel is completely burned, which includes the latent heat of vaporization released when the water vapor in the flue gas condenses into water. It's like when fuel burns, it not only releases the heat of the flame, but also hides the energy when water vapor condenses. The low-level calorific value is the caloric value obtained by subtracting the latent heat of vaporization of water vapor in the flue gas from the high-level calorific value. This can be understood as we exclude the heat released when water vapor condenses and only calculate the heat generated by the combustion of the fuel itself.

The burner system is an important component in boiler operation, responsible for mixing fuel and air for efficient combustion. This article will introduce you to the structure and control principle of the burner system.

In this article, we will explore the working principle, types, and selection criteria of boiler burners, as well as provide practical advice on how to optimize boiler combustion efficiency.

The main factors affecting boiler thermal efficiency include: combustion efficiency (such as incomplete combustion), heat loss (such as high flue gas discharge temperature, boiler wall heat dissipation), operating parameters (such as excess air coefficient), and maintenance and design issues (such as leakage, dust accumulation, etc.). Improving boiler efficiency requires ensuring complete combustion, reducing heat loss, optimizing operation, and strengthening maintenance.
