Drying Refractory in Steam-Generating Boilers - Insulation

Nov 05, 2020 · The main purpose of refractory material that is used inside a marine boiler is to contain the heat generated by burning of the fuel in the furnace and to minimise heat losses from the furnace. It is therefore important that these materials have insulating properties and are able to …

Oil Burner Throat – Reasons for Refractory Failure

May 13, 2010 · Burner throat ensure flame shape, stability and good mixing of fuel and air. Using the right quality refractory and laying it with all precautions will ensure a good life and efficient combustion. Burner throat must be inspected periodically and closely during all the boiler outages. The longitudinal cracks seen on the burner throat surface is not uncommon and is not severe.

Oil Burner Throat – Reasons for Refractory Failure

A castable refractory is generally used for common seals, tube penetrations, and for filling wall-box applications. This type of refractory is the most commonly found refractory on all boilers; it is used on the outside of the steam-generating boilers and is not used inside the boiler/furnace area.

Burner Refractory Castable and Shapes | Cleaver-Brooks OEM

Refractory is used on all steam-generating boilers. Its primary function is to close and seal all openings or gaps so that the fire, heat, gas, and fly ash will not escape the confines of the boiler. Regardless of boiler type, refractory applications are similar, such as refractory-filled wall boxes, refractory on tube walls in non-membrane areas, and at least one large refractory seal somewhere inside the boiler.

FURNACES AND REFRACTORIES

Dec 19, 2016 · Refractories are a vital component in boilers and furnaces, as they serve as a protective lining against the destructive processes of heat, abrasion, and corrosion inside your boiler's combustion chamber. Installing the right boiler refractory materials in industrial and commercial boilers plays a critical role in the efficient and safe operation of your system.

Apr 19, 2021 · Refractory material or brickwork is used on the furnace floor, the burner wall and also behind the waterwalls. The double casing of the boiler provides a passage for the combustion air to the air control or register surrounding the burner. The need for a wider range of superheated steam temperature control led to other boiler arrangements being

How to Destroy a Boiler -- Part 1

Refractory damage is the most prevalent damage associated with a quick warm-up of a boiler from a cold start. Refractory by design transfers heat very slowly and therefore heats up much more slowly than metal. Also, as the air inside the furnace and refractory cool, moisture is absorbed from the air in the refractory.

Powermaster » Refractory

Old boiler designs used refractory material (cement or brick) to isolate those areas of the boiler in which the flame or combustion gases came into direct contact with steel that did not have water on the other side to cool it down. In old fire tube boilers, refractory material was most commonly used in the gas turnaround chamber and in the doors.
