Challenges when Converting Coal-Fired Boilers to Natural Gas

Riley Power recently participated in field testing on a wall fired boiler rated at 1,779,000 lb/hr of main steam flow. The boiler is an opposed fired design with two (2) levels of burners on both the front and rear walls. The natural gas supply system to the boiler utilized a single flow control valve for all the burners.

Typical Causes of Slagging and Fouling Problems in Boilers

The No. 1 cause of furnace slagging is low furnace oxygen content. Most boilers are designed for 115% to 120% theoretical combustion air. This is generally expressed as 15% to 20% excess air. For

Coal-burning boilers were of necessity large as their furnaces were required to accommodate grates, and coal- and ash-handling gear was also large and expensive. As a result, for comparable output the cost of a coal-fired shell boiler was considerably greater than that of its oil- or gas-fired counterpart.

Fire tube or "fire in tube" boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. (Refer Figure 2.2). Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate, but they are limited generally to capacities of 25 tons/hr and pressures of 17.5 kg/cm 2.

Understand Why Furnace Size Varies for Gas, Oil and Coal

Coal fired boiler furnace The coal fired boiler furnace size is generally higher in volume by 20 to 35 %, depending on coal types, when compared to an oil fired boiler. The factors that increase the furnace size are many. The reactivity of coal is much lower than oil and hence need more residence time.

A comparison of fine particulate emissions (3 μm or smaller) based on mass per unit of stack gas between the two boilers, as presented in Table 5, suggested that more fine particles were released from the cyclone equipped oil fired boiler than from the precipitation equipped coal fired boiler. Results of pH and acidity analyses of ash samples indicate that, although sulfur content in oil (1.9%) was lower than …

>Difference between Fire Tube Boiler and Water Tube Boil

Difference between Fire Tube Boiler and Water Tube Boiler

Mar 19, 2016· The main difference between fire tube and water tube is that in fire tube boiler the flue gases flow in the tubes and water flows from the shell and in water tube boiler, water flows from the tubes and the flue gases from the shell or passes over the tubes. This is the key difference between these boilers.
