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.
There are many valves commonly used in atmospheric gas-fired boilers, including gate valves and stop valves of main steam valves, water supply valves, check valves, exhaust valves, etc.
When the water pump is turned on, the pressure signal is transmitted to the on-off valve of the atmospheric gas-fired boiler through the pressure pipe, the valve is opened, and the water circulation is carried out. When the water pump stops, the pressure drops, and the on-off valve is closed slowly to av...
A boiler economizer (also known as an economizer) are mechanical devices intended to reduce energy consumption or perform a useful function such as preheating a fluid. A boiler economizer is essentially a heat exchanger that makes a system more energy efficient by taking enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler – hence recovering more useful enthalpy and improving the steam boiler’s efficiency.
Three-pass steam boilers are so-called because the combustion gases that are produced inside them in the burner go round a circuit that has three parts before leaving it:
Gas-fired boilers are widely applied for civil use and in the industry with high thermal efficiency and good eco-friendly performance. What are the precautions for the commissioning of newly installed gas-fired boilers?
If the final temperature of feed water doesn’t reach the saturated temperature after being heated by an economizer, (that is, the feed water has not reached the boiling state), we call the economizer as a nonsteaming economizer. Generally, the final temperature is 30-50℃ lower than the saturated temperature.
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.
