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...
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?
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...
First of all, the boiler water and steam are two concepts. It is the unit of measurement for boiling water boiler. What is a boiled water boiler? It belongs to the category of normal pressure hot water boiler, which heats the water temperature to boiling state. To ensure safety in use, the top of the boiler is provided with a nozzle communicated with the atmosphere. If steam is discharged automatically, the boiler will always work under normal pressure, so its attribute is normal pressure hot water boiler.
According to the characteristics of biomass fuel, the biomass boiler produced by ZOZEN Boiler has been specially designed in structure, which has taken the lead in solving the problems such as furnace arch collapse, furnace door burn-out, hopper fire and stopper coking.
All boiler pipes have been installed and passed the hydrostatic test.
The furnace wall masonry and insulation work have all ended and has been qualified.
The flue gas duct has been installed and insulated, and the induced draft fan has been installed and debugged to be qualified and can be put into operation.
All the thermal and electrical instruments required for boiler drying have been installed and verified to be qualified.
Mortar samples have been placed on both sides of the middle par...
Chain grate has certain selectivity for coal types, and soft coal with volatile content above 15%, ash melting point above 1250℃, moderate particle size and calorific value above 18800~21000kJ/kg is more suitable.
