test for iron in boiler scale - Bing is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
Technical advantages Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.

Iron Test Kits Iron in industial water treatment is from either the source water supply or is in solution as a result of corrosion. Total iron is the sum of ferrous and ferric forms of Fe in solution. Iron tests are commonly used in boiler and cooling water systems.
In this blog, we are going to cover the chemistry of boiler water test and treatment onboard ship. The boilers are made almost entirely of steel, and iron, The use of sodium carbonate as boiler anti scale, therefore, is not recommendable.

Also included are two 6-inch diameter by 3/4-inch steel crank disks, bronze eccentric, cast iron piston and rings, and all moving parts for the engines. The two engines run on
Common feedwater contaminants that can form boiler deposits include calcium, magnesium, iron, copper, aluminum, silica, and (to a lesser extent) silt and oil. Most deposits can be classified as one of two types (Figure 12-1): scale that crystallized directly onto tube surfaces

– Regularly test the boiler water to determine the dissolved solids and salts. – Chemical dosing should be done as per the test result to keep the boiler scale free. Significance of regular partial blow down: 1. As the temperature rises the chloride comes out of solution that raises the boiler chloride level.
The chloride test is used (often in conjunction with the conductivity test) to regulate boiler blowdown. Blowdown is necessary to keep boiler solids (both dissolved and precipitated) from building up to the level where they might cause scale and carryover. Boiler water chlorides limits are set on the ideas that:

test for iron in boiler scale | Industrial Gas Steam . Boiler water chemical treatment is necessary to prevent or control scale and deposit formation. The formation of scale and sludge can cause tube failures, restrict circulation, reduce system efficiency, and compromise your boiler system's reliability.
The consensus is that feedwater oxygen, iron, and copper content should be very low (e.g., less than 7 ppb oxygen, 20 ppb iron, and 15 ppb copper for a 900 psig boiler) and that pH should be maintained between 8.5 and 9.5 for system corrosion protection.
