helamine boiler 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.
Boiler water treatment with Kurita's Cetamine® Technology provides: Flexible treatment programs for boiler operation in continuous or discontinuous mode. Preparation of shell boilers and water-tube boilers for system shut-downs.
In the boiler water of steam generators the polyelectrolytes have a synergetic effect. The polycarboxylates (as sodium salt) cause at every temperature an alkalinization because of hydrolysis. As a polyelectrolyte it has greater affinity to bivalent cations (e.g. Fe 2+ or Ca 2+), like a weak acidic ion exchanger. Hence, quite stable calcium or ...
Helamin forms a firmly adhering protective film, which prevents corrosion and fouling on the water-side walls in steam boilers and piping systems. It happens because Helamine has an affinity to metal and oxide surfaces. Crystals which do form in the presence of Helamine are isolated, so that they cannot group themselves any longer. Thus deposit
Boiler corrosion control; Oxygen-related metallic corrosion is a significant issue in the operation and maintenance of industrial boiler systems and steam raising plant. To ensure that such boiler systems are well maintained and operate at optimum efficiency it is essential that the correct water conditions are maintained at all times.
HELAMIN 906 H. Environmental compatible scale and corrosion inhibitor for the treatment of high pressure steam boilers and hot water systems utilizing softened or demineralised make up water. The way it works A hydrophobic film containing magnetite is formed by a molecular bond with the surface of the metal. In addition to excellent metal ...

The HP plant is a standard unit with a Benson-type once-through boiler with single reheat and with an extraction condensing turbine. Pressurised water flows through the boiler, is heated and evaporated. Main steam (540°C, 200 bar) supplies the HP part of the turbine. Partially expanded steam then passes through the reheater.
Crystals which form in the presence of Helamine are isolated, so that they do not tend to group themselves. Thus deposit consolidation is inhibited. Already existing oxide surface deposits are gradually removed. In the boiler, a fine, liquid mud, which is easier to remove from the boiler walls, develops.

boilers, and reduce pipe wall thinning due to flow-accelerated corrosion. Introduction: The presence of dissolved oxygen in boiler feedwater and steam generating systems can present serious problems in a steam generating plant by promoting corrosion and thick scale formation in the feedwater system, the boiler, and the steam condensate system.
