phosphate in boiler water 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.
2019-5-8 · Boiler water is the liquid phase of steam within a boiler.The term may also be applied to raw water intended for use in boilers, treated boiler feedwater, steam condensate being returned to a boiler, or boiler blowdown being removed from a boiler.
2016-11-3 · When using phosphate boiler water treatment, the concentration of phosphate should not exceed the equilibrium concentration.This is the maximum concentration of PO4 in the boiler water that the boiler can tolerate under the highest heat flux conditions (full load).
2019-5-24 · Phosphate buffers the boiler water, reducing the chance of large pH changes due to the development of high caustic concentrations. Excess caustic combines with disodium phosphate and forms trisodium phosphate. Sufficient disodium phosphate must be available to combine with all of the free caustic in order to form trisodium phosphate.
Alibaba offers 443 phosphate in boiler water products. About 20% of these are phosphate. A wide variety of phosphate in boiler water options are available to you, such as sodium hexametaphosphate, monopotassium phosphate, and sodium phosphate.
2014-5-15 · The boiler water and boiler feed water were analyzed regularly as a part of monitoring program, a typical operation limits of the second period are shown in table (1). Table 1: Operation limits of boiler feed water and boiler water, when congruent phosphate treatment was used. BFW BW pH 8.8-9.3 9-10 Conductivity (µS/cm2) 1-2.6 5-30
2011-1-31 · Phosphate hideout is a phenom-enon that causes boiler water control difficulties. It is defined as the disappearance, by precipita-tion or absorption, of the ionic phosphate (PO 4) species, in the boiler water under high heat transfer or high load conditions. When the high heat flux or high load condition is reduced, the species (phosphate
Boiler Scale Inhibitors 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
2016-12-14 · Plant Service Bulletin Boiler Water Phosphate Chemistry 00 Purpose The purpose of this bulletin is to re-emphasize to all utility operators the potential chemistry control prob- lems that can lead to serious furnace tube corrosion. Monitoring of boiler water chemicals has always been necessary. However, units operating at high drum
