water–wall.Water-wall tubes wear is one of the most serious problems of CFB boiler.
If [H] can’t be taken away by cycling water and steam, it would cause water-wall tubes hydrogen corrosion.
As a result, on the water-wall weld position, the upper and lower water-wall were not on one line, when installation forcibly welded fins due to the water-wall inherent stress combined with wear caused divulge.
On 7 December, 2010, the water-wall between #1boiler furnace let out two flue ducts tube-bursts, as the installation fin for water wall were irregular flat irons, which will result in water-wall fins bulge.
Conclusions Failure of the boiler heat tube is a multidisciplinary, many professional compound and multi-disciplinary engineering problem.

Although there are standard methods such as AATCC195-2009 [9] and maturely applied instrument MMT [10], which can be employed to measure the fabric moisture management properties including water absorbency, water repellency and overall moisture management properties, the measurement system reported in this paper focuses on the characterizing method of liquid moisture transfer difference between two surfaces of textile fabrics, which is the most important parameter to reflect the dynamic liquid moisture transfer properties and comfort sensations of textile materials.
There is a fine water pipe fixed through the central sensor of the upper measuring head, which can supply a predefined amount of test solution (synthetic sweat) with the water storage box and control system during testing.
By testing the resistance changes between the measuring rings of sensors, which will reduce when the fabric is wet or contains a quantity of moisture, the changes of water and liquid moisture content on the fabric upper and lower surfaces (UU and UL) can be measured.

What's worse, their technological resources are rather disperse and have no perfect facilities for providing professional technological services, research and development and training.
Some of the citizens of other places in Harbin have moved to high buildings equipped with water, electricity and gas, while the workers here are still living in the easily-built houses established in the early start of the 1950s; the street blocks of their residence sees shrinking commercial services and business circles with each passing day.
