Excess air ratio is a term used to describe the amount of air supplied to the combustion process in a boiler compared to the theoretical amount required for complete combustion. It is defined as the ratio of the actual amount of air supplied to the combustion process to the amount of air required for stoichiometric combustion.
In an industrial boiler, excess air is supplied to ensure that all of the fuel is burned completely and efficiently. The excess air ratio is usually expressed as a percen...
Industrial boilers are an essential part of many manufacturing processes, providing the steam and hot water needed to power machinery and heat buildings. However, they can also be a significant source of energy consumption and greenhouse gas emissions, making it essential to ensure that they operate as efficiently as possible. In this article, we'll explore five ways to increase the efficiency of your industrial boiler, helping you to reduce operating costs, improve sustainability, and enhance p...
There are many factors that can affect the main steam pressure of industrial boilers, including:
1. Quality of fuel and combustion method: The quality of fuel and combustion method directly affect the temperature and pressure in the furnace, which in turn affects the size of the main steam pressure.
2. Water quality: The quality of water is crucial for the thermal efficiency and safe operation of boilers. If there are a large amount of impurities and hardness substances in the water, it will c...
Drying the moisture in the fuel of a biomass-fired boiler is important to ensure efficient combustion and prevent issues such as fuel bridging, clumping, and poor boiler performance. Here are some methods that can be used to dry the moisture in biomass fuel:
1. Sun drying: This method involves spreading the biomass fuel, such as wood chips or sawdust, in a thin layer in a sunny, well-ventilated area. The sun's heat and wind will help to evaporate the moisture in the fuel.
2. Fo...
There are several reasons why a gas steam boiler may automatically shut down. Here are some of the common reasons:
1. Low water level: If the water level in the boiler falls below a certain level, it can cause the boiler to automatically shut down to prevent damage.
2. High pressure: If the pressure in the boiler exceeds a certain level, it can cause the safety valve to open and the boiler to shut down.
3. Flame failure: If the flame in the burner fails to ignite or is extinguished during ope...
The normal temperature of the combustion chamber in a biomass boiler can vary depending on the type and design of the boiler, as well as the specific fuel being used. Generally, the combustion temperature in a biomass boiler can range from 800 to 1200 degrees Celsius (1472 to 2192 degrees Fahrenheit).
However, it's important to note that the temperature of the combustion chamber should be monitored regularly to ensure safe and efficient operation. If the temperature is too low, it can result in...
The steam drum wall in a boiler refers to the wall of the steam drum, which is one of the important components of the boiler. The steam drum wall is generally made of corrosion-resistant alloy steel plates under high temperature and pressure, and has high strength and corrosion resistance.
The steam drum is an important component in the boiler and mainly acts as a buffer between steam and liquid water. When water enters the steam drum from the pipeline, it turns into steam and accumulates at th...
The water level of steam drum can reflect the condition between feedwater quantity and evaporation quantity of boiler. If the two parameters maintain a stable balance, the water level also remains unchanged; otherwise, the water level will rise or fall. Besides, there is also a false water level phenomenon. How do we understand the false water level?
