Replacements available for Steam Boiler Water and High Temperature Hot Water Bundles. Cemline standard replacement tube bundles are designed for a maximum working pressure of 150 psig and a temperature of 375 oF. Normal construction and various options are outlined below.
Unfired steam boiler tube bundles and/or drum can be fabricated using materials that will be cost effective for the process steam condition. These can range from copper tube bundles and pressure vessel quality steel to tube bundles made from cupro-nickel or stainless steel tubing and drums fabricated with stainless steel.
On the heating surface of superheater and economizer tube bundle of the boiler in order to prevent the pipe from being worn by high temperature flue gas washing boiler tubes erosion shields are mostly arranged on the outer side of the pipe in the direction of flue gas flow. The elbow erosion shields solves the abrasion problems of water wall ...

Staggered tubes proved 10-pass self baffled heating surface for high efficiency as well as ASME tube bundles offer extreme flexibility for long boiler life. A Sealed Combustion Chamber for low excess air level and high efficiencies.
As its name implies this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it. One fluid runs through the tubes and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids.
