However, the boiler was never so important as during the industrial revolution and the invention and heavy use of steam-powered trains and boats. About 100 years ago, boiler manufacturers focused heavily on the invention of boilers for these two uses. There were many reasons why people liked steam boilers better than coal-powered trains and boats.

Gas boilers burn natural, process, landfill, coal-derived, refinery, hydrogen and/or bio gas(es), no solid fuels, and may fire liquid fuel during periods of gas curtailment, gas supply interruption, startups, or periodic testing on liquid fuel. Periodic testing of liquid fuel shall not exceed a combined total of 48 hours during any calendar year.

Pages Introduction

To overcome this delay, boilers designed for coal firing need to contain more water at saturation temperature to provide the reserve of energy to cover this time lag. This, in turn, means that the boilers are bigger, and hence more expensive in purchase cost, and occupy more valuable product manufacturing space.

What Causes Clinkers in Coal Fired Boilers? Hunker

Coal boilers draw their combustion air from the bottom, up through the combustion grate. Lots of large clinkers on the combustion grate can hinder air passage, increase operation and maintenance costs and even force shutdowns of the boiler for cleaning out the clinkers.

It is a manufacturing process that converts any material containing carbon—such as coal, petroleum coke (petcoke), or biomass—into synthesis gas (syngas). The syngas can be burned to produce electricity or further processed to manufacture chemicals, fertilizers, liquid fuels, substitute natural gas (SNG), or hydrogen.

Pulverised Coal Combustion with higher efficiency

This process heats water in tubes in the boiler so that it becomes steam at a pressure of around 180 bar and a temperature of 540 o C. This steam is passed into a turbine to produce electricity (see Figure 1). Pulverised coal power plants account for about 97% of the world's coal

Economizers CleanBoiler.org Boiler Consortium

Economizers designed for natural gas only, would likely plug-up if installed on a coal boiler and would face increased risk of corrosion if installed on an oil-fired boiler. Some units are designed to keep the flue gases above condensation temperature, and others are made of materials that resist the corrosive effect of condensed flue gases.
