As a new mature high-efficiency and low-pollution clean coal technology, circulating fluidized bed combustion (CFBC) technology has many advantages that other combustion methods do not have. Circulating fluidized bed combustion is low-temperature combustion, so the NOx emission is much lower than that of pulverized coal furnace, only 200ppm.
Hot-water boiler is a kind of thermal equipment that uses the heat energy released by fuel combustion or other heat energy (such as electric energy, solar energy, etc.) to heat water to the rated temperature. According to different fuels, hot water boilers can be divided into gas-fired hot water boilers, oil-fired hot water boilers, biomass-fired hot water boilers, and coal-fired hot water boilers. How to choose hot water boiler? We will focus on the heating, pressure and thermal efficiency of hot water boiler.
The rated output of boiler refers to the maximum sustained output of industrial boiler under rated parameters (pressure and temperature) and certain efficiency. For steam boilers, the rated output is also called rated capacity, and the unit is t/h (tons/hour); For a hot water boiler, the rated output of the boiler is also called the rated thermal output, and its unit is MW.
In boilers, economizers are heat exchange devices that heat fluids, usually water, up to but not normally beyond the boiling point of that fluid. Economizers are so named because they can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler, thereby recovering more useful enthalpy and improving the boiler's efficiency. They are a device fitted to a boiler which saves energy by using the exhaust gases from the boiler to preheat the cold water used to fill it (the feed water).
Industrial heat exchangers come in a variety of sizes and styles, including:
Double pipe heat exchangers are the simplest exchangers used in industries. On one hand, these heat exchangers are cheap for both design and maintenance, making them a good choice for small industries. On the other hand, their low efficiency coupled with the high space occupied in large scales, has led modern industries to use more efficient heat exchangers like shell and tube or plate.
Shell-and-tube heat exchanger...
As we all know, energy efficiency is important. If you’re a plant manager or industrial facility owner, there may be one place where you’re overlooking efficiency: the industrial heating equipment that powers your facility.
Efficiency is especially important on a large scale and manufacturing and production operations are no exception. Here are two key reasons why you may want to consider upgrading your industrial heating equipment or installing a new, highly efficient therm...
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.
As we all know, the stable operation of the natural gas boiler can significantly optimize the operation of the boiler, improve the efficiency of the boiler, and effectively reduce the operating cost of the boiler after effective maintenance. So, what factors will affect the stable operation of natural gas boilers?
