Coal-Fired Boiler: A Comprehensive Expert FAQ Guide

Are you searching for an affordable industrial Coal-Fired boiler?  With over four decades in the coal-fired boiler manufacturing industry, our products are guaranteed to meet all your needs. Here are a few frequently asked questions that will guide you in your search for the most appropriate boiler;

How does your Coal-Fired Boiler work?

A utility Coal-Fired Boiler produces thermal energy by igniting coal. Yongxing Coal-fired boiler works by burning coal in your chain grate stoker, thus heating the whole unit. The water in the boiler will become hot and generate steam which offers heat energy.

Our image below illustrates how our Coal-fired boiler works.

Coal fired boiler system

Yongxing boiler is pre-set to run on AII bituminous coal or anthracite with a heat value ranges from 4500-6000 kcal per kilogram.

Even you have a very low calorific value of coal and would like a boiler that can run on it. You don’t have to worry because we could build a big volume boiler furnace, long grate stoker, and secondary fan to support the combustion.

We will assemble a full set of control monitoring instruments for you. The coal-fired boiler working is safe and reliable.

A coal-fired boiler produces loads of ash during the process of combustion. You have to remove ash at the bottom of the boiler constantly to keep your boiler in good condition. Numerous businesses use Coal-Fired Boilers for a wide array of operational functions.

How To Calculate Coal-fired Boiler Efficiency

The basic formula to calculate Coal-fired boiler efficiency is η= (Energy output)/ (Energy input) X 100. Essentially, you have to divide the overall energy output of your boiler by the aggregated energy input given to it.  This 3-D image below shows all the sub-systems of your Coal-fired boiler that collectively contribute to your boiler’s overall efficiency.

SZL-double-drum-coal-biomass-boiler-system

Coal-fired boiler efficiency is a collective efficiency outcome of all constituents that make up the boiler. A coal-fired boiler has several sections. If any unit fails to work at an optimum level, it will have a negative impact on the Coal-fired boiler’s overall efficiency.

It is also important to note that the Bag filter effectively regulates both whole and fine particulate matter. The image below is a simplified schematic illustration of a Bag Filter Coal-fired boiler;

How are your Coal-fired Boiler Emissions?

The Coal-fired boiler emissions factor ranges from 30mg/Nm3 to 300mg/Nm3. This emissions rate falls within the boundaries of the industry’s recommended standards. Atmospheric emissions from Coal-fired boilers can pose several serious adverse effects to human health and the environment. The legislation was put in place to ensure that such emissions are controlled to minimize environmental damage and human health risks.

Our Coal-fired boiler emissions rates are excellent as far as industry standards and governmental regulations are concerned. You can minimize your boiler emissions by using quality anthracite coal and regular maintenance on your Coal-fired boiler. Your Coal-fired Boiler comes with a comprehensive user manual that guides you on ideal operation and avoidance of unnecessary emissions.

What is the difference between Coal-fired boilers vs. Oil-fired boilers?

The difference between a Coal-fired boiler versus an Oil-fired boiler is pretty straightforward.  A coal-fired boiler uses Coal, whereas an Oil-fired boiler uses oil. In a Coal-fired boiler, Coal is ignited to generate thermal energy. It would be best to use a specific type of Coal known as anthracite Coal in your Coal-fired boiler.

In an Oil-fired boiler, you have to use light oil, diesel, gasoline, heavy oil, or waste oil. Oil-fired boilers are more costly to operate and maintain than coal-fired boilers because Coal is cheaper than oil. You also have to note that Coal-fired boilers are more environmentally friendly than Coal-fired boilers. Coal-fired boilers have better harmful emissions control devices than Oil-fired boilers.
