Boiler is a kind of thermal energy conversion equipment composed of drum and furnace. It uses fuel combustion to heat water into steam or hot water to provide power for production or help auxiliary production. With the continuous improvement of industrial manufacturing technology, boiler's control has also changed from the traditional full manual operation to the present automatic intelligent control.
With the upgrading of energy-saving technology of industrial boilers, condensing boilers with higher thermal efficiency are widely used. Some users will find that there is water flowing out of the tail of the boiler flue during use, they may consider the situation as the boiler is leaking, but it is actually condensed water in the boiler. This paper introduces how the condensed water in the boiler is formed and how ZOZEN Boiler uses the condensed water in the boiler.
How is the condense...
The relationship between a boiler's flue gas volume and temperature is a complex interplay of various factors that depend on the boiler's design, type of fuel used, combustion efficiency, and operational settings. However, some general principles can help elucidate the relationship:
Combustion Efficiency: In an ideal combustion scenario, all the fuel would burn completely, generating water vapor and carbon dioxide primarily. However, real-world combustion is rarely perfect. Incomplete c...
Steam boilers play a vital role in various industrial and commercial processes. However, like any mechanical system, they come with their challenges. One such issue that operators commonly face is the condensate return problem. Addressing this effectively ensures not only the boiler's efficiency but also its longevity and safety.
Understanding Condensate Return:
When steam releases its latent heat, it condenses back into water. This condensed water, known as condensate, is pure, hot, a...
A "Full Premix Condensing Boiler" represents the pinnacle of heating technology and efficiency. This innovative system, a core product of ZOZEN Boiler, exemplifies our dedication to reducing emissions and energy consumption in heating.
"Full premix" signifies an advanced combustion process that we have adopted, where the fuel and air are completely mixed in the correct proportions before being ignited. This results in a more complete and efficient combustion, allowing for maximum heat extractio...
Boiler economizers are devices that help to improve the efficiency of industrial boilers by recovering heat from the flue gas and transferring it to the boiler feedwater. In this article, we will explore how boiler economizers work and the benefits they offer. We will also introduce ZOZEN's boiler and economizer solutions that can help improve the energy efficiency of your industrial operations.
How Do Boiler Economizers Work?
A boiler economizer is essentially a heat exchanger that recovers w...
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.
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...
