The pharmaceutical sector is an area that requires the highest quality steam for its processes, known as clean steam, instead of other industrial steams. Some processes in this sector even need the highest level of quality - pure steam, which involves even stricter steam purity requirements for use in the sterilization of raw materials and pharmaceutical products at high temperatures.
Discharging high-temperature flue gas generated by a biomass-fired boiler efficiently and safely is crucial for boiler operation, environmental compliance, and energy recovery. These gases, if not handled properly, can lead to energy inefficiency and increase the emission of pollutants. ZOZEN Boiler, as a professional industrial boiler manufacturer, incorporates advanced technologies and strategies to manage and utilize high-temperature flue gases from biomass-fired boilers. Here's an overview o...
As a kind of special equipment, the safe operation of industrial boilers is the key point that every enterprise may pay attention to. Today, let’s talk about the normal water level in boiler operation.
During the normal operation, the steam drum water level maintains 0mm, and the allowable fluctuation range is ±30mm, with the maximum not exceeding ±50mm.
Boiler water circulation refers to the circulating flow of water and steam-water mixture on the evaporating heating surface of boiler. What is the working principle of the latest water circulation system of boiler?
To guarantee the successful and efficient shell boiler operation, the user must:
1)Know the conditions, environment, and demand characteristics of the plant, and accurately specify these conditions to the boiler manufacturer.
2)Provide a boiler house layout and installation that promotes good operation and maintenance.
3)Select the control systems that allow the boiler to operate safely and efficiently.
4)Select the control systems that will support the boiler in supplying dry steam to the plant at the required pressure(s) and flowrate(s).
5)Identify the fuel to be used and, if necessary, where and how the fuel reserve is to be safely stored.
System load is measured in either BTUs or tons of steam (at a specific pressure and temperature). It would be nearly impossible to size and select a boiler(s) without knowing the system load requirements. Knowing the requirements leads to the following information:
The boiler(s) capacity, taken from the maximum system load requirement.
The boiler(s) turndown, taken from the minimum system load requirement.
Conditions for maximum efficiency, taken from the average system load requirement.
Determining the total system load requires an understanding of the type(s) of load in the system. There are three types of loads: heating, process, and combination.
(Question Details) Specific Performance:(1) There are blasting sounds in the furnace, and the furnace chamber is under positive pressure. There is smoke emitted from the combustion chamber in a leakage. In severe cases, the explosion-proof door of the boiler body opens.(2) Drum water level drops rapidly and the feedwater flow rate is not abnormally larger than steam flow. MFT acts when the water level is below -280mm.(3) Drum pressure, steam flow rate, exhaust temperature decrease, smoke temperature difference increases on both sides.(4) The negative pressure at the inlet of the flue and suction fan becomes smaller and the temperature difference between the two sides increased. (5) Smoke temperature decreases at the inlet and outlet of the cyclone separator, and the temperature of the material returned is low.(6) Bed pressure increases, bed materials clean, fluidization poof, bed temperature distributes unevenly and bottom slag discharge difficultly. Answer：cause of failure:(1) Fly ash
