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.
Biomass boilers do produce emissions when they burn organic materials such as wood chips, pellets, or agricultural waste. The exact type and amount of emissions depend on various factors such as the type of fuel used, combustion efficiency, and air pollution control technologies in place. However, with proper design and operation, biomass boilers can emit significantly less pollutants than traditional fossil fuel boilers, making them a more environmentally friendly option for heat and power...
When it comes to coal fired boilers, the rear arch plays a critical role in the combustion process. The main function of the rear arch is to keep the fuel particles in suspension and prevent them from falling into the ash hopper, which can lead to incomplete combustion and decreased efficiency.
At ZOZEN, we understand the importance of a well-designed rear arch for coal fired boilers. That's why our coal fired boilers are equipped with advanced rear arch designs that enhance the combust...
An Interlock in the boiler’s control system is a programmed or hardwired condition that forces a device to be in a pre-determined or permissive state before the process can continue.
Depending on design pressure, fuel type, either liquid, gas or solid, all steam boiler require interlocks to sequence the operation and to prevent damage to the boiler. Examples of such devices are High or Low Boiler Drum Water Level, Low Boiler Feed Pump Pressure, High or Low Fuel pressure, High or Low Atomization pressure (oil fired), Proof of Ignition, Proof of Flame, FD and/or ID (solid fuel) Fan Motor Operation or combustion air pressure, Damper or Valve position and High Boiler Steam Pressure as well as O2 and furnace temperature.
The design and construction of gas boiler room is also a very important point in boiler safety. How to install the gas boiler should also conform to the boiler room design specification, and it is necessary to comply with the site, space, protection and other aspects.
How to install the gas boiler?
How to install the gas boiler is mainly based on the Boiler Room Design Code and Boiler Safety Technical Inspection Code. In addition, the Urban Gas Design Code and the Fire Protection Code ...
As a clean fuel, natural gas has much lower sulfur content and nitrogen content than coal, and there is no ash in the fuel, and the flue gas produced after combustion is almost smoke-free. Therefore, a nationwide upsurge of coal to gas has been set off.
However, there are some problems in the process of gas boiler operation, among which the hardness, harm and treatment of gas boiler flue gas condensate are prominent.
When the boiler flue gas temperature is lower than the dew po...
The main working principle of industry is a kind of heating equipment which uses the heat energy released after fuel combustion or the waste heat in industrial production to transfer to the medium in the container, so that the medium can reach the required temperature, and then it can be transported to the heating process for heat exchange. According to different media, boilers can be divided into many types.
Types of boiler heating medium
1. Steam, steam boiler and superheated steam b...
Industry boiler is an important thermal power device, which is widely used in factory power, building heating, people's life and other aspects, with a large demand and a wide variety. According to the different flue gas passes, gas-fired boilers are divided into two-pass and three-pass boiler structures. Here, ZOZEN Boiler focuses on the structure and process principle of the common three-pass boiler.
The first pass: after the fuel is atomized by the burner, the formed torch is filled i...
