Our Lastest Boiler Type

Seven Hold Points

Seven hold points are set and each one is supervised by a responsible inspector. Any work that fails to pass the inspection cannot proceed until the inspector is able to verify its quality.

1,Incoming materials are inspected again upon entry into the plant.

2,Material markings will be transferred to all cut pieces to ensure identification and traceability.

3,Test pieces are used to ensure a higher success rate in welding.

Methods of Firing Steam Boiler | Electrical

When fuel i.e. coal is put into the steam boiler furnace by means of a mechanical stoker, the firing of boiler method is referred as mechanical stoker firing.There are mainly two types of mechanical stoker firing systems.. Under Feed Mechanical Stoker Firing. Here, combustion takes place on the grate.

Grate Limit and Boiler Efficiency | Advanced Steam Tracti

In the diagram, k 1 is the maximum predicted boiler efficiency (at zero firing rate) and k 2 is the slope of the straight line relating efficiency to firing rate. [A simple mathematical proof that (based on Fry’s equation) the boiler efficiency at the grate limit is exactly half the maximum efficiency is given further below.

Cofiring - Wikiped

For example, in a pulverized coal power station a grate firing system may be installed at the bottom of the combustion chamber, though this solution is rare. Indirect co-firing systems imply usually more complex and expensive solutions, but they reduce usually problems related with corrosion, fouling, slagging, etc. This, a priori, allows co
