Overheating in the combustion engine of a gas-fired boiler can be caused by several factors. Understanding and addressing these issues is crucial for maintaining the efficiency and longevity of the boiler, as well as for ensuring safety. Here are some common causes of overheating in the combustion engine of a gas-fired boiler:
Insufficient Water Flow: If there isn't enough water flowing through the boiler, it can't absorb enough heat from the combustion process, leading to overheating. This cou...
Choosing a thermal fluid (also known as a heat transfer fluid or HTF) for an industrial boiler application is a critical decision, as it directly impacts the safety, efficiency, and performance of your heating system. Here’s a step-by-step guide to help an industrial boiler buyer or manufacturer choose the right thermal fluid:
1. Operating Temperature Range:Determine the required operating temperature range of your application. Choose a thermal fluid that has a bulk temperature operating ...
There are several ways to estimate the thermal efficiency of gas-fired boilers:
1. Direct method: This method involves measuring the amount of fuel consumed and the amount of heat produced by the boiler. By comparing these two values, it is possible to calculate the thermal efficiency of the boiler.
2. Indirect method: The indirect method involves measuring various parameters such as flue gas temperature, ambient air temperature, and fuel consumption, and then calculating the t...
Gas-fired boilers use gaseous flammable gases (including liquefied combustible gases) as fuel. These gaseous fuels have relatively higher calorific value and less pollutant emissions, and are gradually becoming popular among corporate users.
Proper shutdown procedures are crucial for ensuring the safe and efficient operation of a coal-fired steam boiler. The following steps should be followed when shutting down a coal-fired steam boiler:
1. Reduce the load: Before shutting down the boiler, the load should be reduced to its minimum level. This will help to prevent sudden drops in pressure and temperature, which could cause damage to the boiler and its components.
2. Shut off the fuel supply: The fuel supply to the boiler should be ...
Oil-fired hot water boilers are hot water equipment that is widely used in industrial and civil fields. However, sometimes during use, oil-fired hot water boilers may emit a large amount of white smoke. What is the cause of this?
Firstly, the reason for the oil-fired hot water boiler emitting a large amount of white smoke may be incomplete combustion of the boiler. This may be due to insufficient oil supply, poor oil quality, excessive deposits inside the combustion chamber, and other i...
Economizer
Increase the heat exchange area of the boiler economizer. For example, adopting the economizer whose actual internal area is 1-2 times larger than the ordinary can effectively reduce the flow rate of flue gas, improve the heat exchange efficiency and lower the exhaust gas temperature.
Air preheater
An air preheater is installed with the connected pipe behind the economizer, which can effectively increase the air temperature for supporting the combustion, improve the fuel ignition ...
Boiler furnace is a three-dimensional space surrounded by furnace walls, which is used for burning fuel. The function of the boiler furnace is to ensure that fuel is burned out as much as possible, and to cool the flue gas temperature at the outlet of the furnace to the temperature allowed by the safe operation of the convection heating surface.
