Furnace tube in Biomass boiler membrane wall ASME or ISO 3834 EN standard

Boiler Maintenance

1. In maintenance of industrial high pressure steam boilers panel wall cold cutting is an important step before weld preparations.

2. To avoid any heat affected zone (HAZ) on the boiler tubes of the water wall panels, the sawing of the defective panel wall tubes should be done not by flame cutting but instead with the BWC cutting system, that uses abrasive saws.

3. The system increases safety of workers and works with high productivity.

4. Due to the straight cut you will have less wearing of cutting discs and caused by the high cutting quality you have less after work, after removing boiler tube failures.

Related Package Boiler

1. Package boilers are commonly called water or fire tube Boilers. Water tube boilers use convection heating, which draws the heat from the fire source, and passes against the generating tubes of the boiler, causing water inside those tubes to boil off into steam.

2. The fire tube boiler arrangement utilizes conduction heating which transfers heat from physical contact. Fire tube boilers are not commonly used due to their method of conduction heating because pipes in direct contact with fire and cold water could damage the pipes.

3. The package boiler is usually a two or three-pass fire-tube boiler with an internal furnace tube. This is similar to the much earlier Scotch boiler.

Advantages

1. The protective effect of membrane water cooling wall on the furnace wall is the most complete, so the furnace wall only needs insulation materials, rather than refractory materials, so that the thickness and weight of the furnace wall are greatly reduced, simplify the structure of the furnace wall, reduce the total weight of the boiler.

2. Membrane water wall also has good air tightness, can adapt to the requirements of positive pressure combustion on the boiler, not easy to slag formation, less air leakage, reduce the heat loss of smoke exhaust, improve the boiler thermal efficiency.

3. it can be welded into components by the manufacturer for quick and convenient installation.

4. the use of membrane wall structure of the boiler, simple maintenance, boiler service life can be greatly improved.
