Sep 06 2019 · As temperatures continue to rise and excess water remains in the lining steam spalling becomes increasingly likely. 7. Avoid surface coating. An impermeable coating on the refractory surface will prevent the stage one escape of water from the lining and pressure will increase as superheated steam builds up behind the impermeable layer. Rotary kilns for iron-ore pellets production are highly dependent on a well-functioning refractory brick lining. To improve the long-term capability of the lining in-situ observations of the bricks performance are desired however the high process temperatures and the size of the kiln make it difficult to study the lining during operation.

Journey for Air Cooler Heat Exchanger Tenova Pyromet

During an inspection in 2013 Northam Platinum identified that the refractory lining on its 15 MW furnace had eroded prematurely. As a remedy Northam Platinum decided to implement the recommended plate cooler solution and to install a new refractory lining. The loads generally acted on the refractory lining coming from abrasion of clinker ball abrasion and chemical reaction of clinker dust and strong thermal cycling of secondary air from cooler as showed in figure 1. However improper installation and installation techniques also

Looking for 1950 API-ASME Code Allowable StressBoiler

Feb 16 2011 · I ve found the allowable stress for A-70 in the 1943 API-ASME code but A-285-C replaced A-70 in 1947. In the 1951 API-ASME code A-285-C stops at 900 F. The client no longer has the design calculations and we re trying to reproduce some of the calculations for them. The process in the vessel operates at 950 F with some internal refractory lining. Understanding Refractory API 936 Reading II. 1. Scope 1.1 This test method covers the determination of the permanent linear change of refractory brick when heated under prescribed conditions. 1.2

shell stresses in a carbon steel stack from sling loads

In the most simplistic form the stack is a simple beam with a distributed load due to self weight combined with the refractory lining weight. If the lining is effectively bonded to the shell then the bending stresses will be shared across the combined section. You may need FEA to analyse what is happening in the lining Resco is a leading supplier of brick and monolithic refractories in the paper industry.
