A boiler that runs on hard feed water and a loose blowdown schedule tells you something is wrong long before it fails: the stack temperature climbs, the fuel bill follows, and the tube sheet starts to show the first hard deposits. In Nepal's industrial steam plants — sugar mills, cogeneration units, pharmaceutical and food processing boilers — the water chemistry varies widely with the source, and the treatment programme has to be built around the analysis, not around a fixed product package. Innovacorp manufactures and supplies boiler water treatment chemicals for industrial plants in Nepal — scale inhibitors, sludge conditioners, oxygen scavengers, alkalinity builders and condensate treatment chemicals — selected on the feed water and boiler water analysis, not on a fixed catalogue.

Why Boiler Water Treatment Is a Programme, Not a Product

A boiler water programme has four distinct problems to handle, and they need different chemistries:

• Scale — calcium and silica deposits on the tube surface. Handled by scale inhibitors (antiscalants) that keep the salts in suspension so they leave with the blowdown.
• Sludge and suspended solids — the solids that form from the scale-inhibitor action and from the feed water itself. Handled by sludge conditioners (dispersants) that keep them fluid and removable.
• Corrosion — oxygen pitting, carbonic acid attack in the condensate, and caustic embrittlement at high alkalinity. Handled by oxygen scavengers, alkalinity builders and condensate treatment chemicals.
• Carryover — foam and priming that carry boiler water into the steam. Handled by antifoams and blowdown control.

No single product handles all four. The programme is set on the water analysis, the boiler pressure and the blowdown practice — and it is reviewed through the year as the feed water quality changes.

The Product Families We Manufacture and Supply to Nepal

Product family	What it does	Typical dose
Scale inhibitors (antiscalants)	Keeps calcium and silica in suspension so they leave with the blowdown.	5–30 ppm in boiler water — confirmed after analysis.
Sludge conditioners (dispersants)	Keeps suspended solids fluid and removable through blowdown.	5–20 ppm in boiler water — confirmed after analysis.
Oxygen scavengers	Removes dissolved oxygen before it causes pitting in the boiler and the economiser.	Set on the dissolved oxygen in the feed water.
Alkalinity builders	Holds boiler water pH in the mildly alkaline band and supports the magnetite layer.	Set on boiler water pH and total alkalinity.
Condensate treatment chemicals	Neutralises carbonic acid in the condensate return, protects the return lines.	Set on condensate pH and CO₂ load.

The exact product mix and dose are confirmed after a feed water and boiler water analysis. We do not recommend a fixed package for every plant — the water chemistry decides.

How Each Product Family Works

• Scale inhibitors: Polymer or phosphonate based. They work by threshold inhibition (preventing crystal growth at sub-stoichiometric doses), crystal distortion (changing the crystal shape so it does not adhere to the tube), or dispersion (keeping particles suspended). Silica scale needs a different chemistry from carbonate scale.
• Sludge conditioners: Dispersants that keep suspended solids from agglomerating and settling on the tube surface. They work alongside the scale inhibitor — the inhibitor prevents scale from forming, the conditioner keeps the resulting solids moving.
• Oxygen scavengers: React with dissolved oxygen in the feed water before it reaches the boiler, where it would cause pitting in the economiser and the boiler tubes. Sulfite, DEHA and carbohydrazide grades cover different pressure ranges.
• Alkalinity builders: Raise the pH and total alkalinity into the recommended band, holding the magnetite layer and reducing the CO₂ load on the condensate side.
• Condensate treatment: Neutralising amines or filming amines that protect the condensate return lines from carbonic acid corrosion.

Where Each Product Fits in a Nepal Plant

• Low-pressure boilers: Scale and sludge control, oxygen scavenging and alkalinity control for process steam.
• Medium-pressure boilers: Full programme — scale, sludge, oxygen, alkalinity and condensate — matched to the boiler pressure.
• Sugar mill and cogeneration boilers: Deposit and corrosion control in bagasse-fired boilers, where the feed water quality varies with the season.
• Pharmaceutical and food processing boilers: Programme tuned to the steam quality requirement of the process.

Specifications

Grade-wise technical data — appearance, active content, pH, density and shelf life — is shared as a TDS on request for the specific product under consideration. Final specification is confirmed against the product TDS before dispatch.

Dosage and Feed Point

Dose is set on the feed water and boiler water analysis, not a fixed figure per tonne of steam. Working reference ranges for Nepal plants:

• Scale inhibitors: 5–30 ppm in boiler water, adjusted to the calcium and silica load.
• Sludge conditioners: 5–20 ppm in boiler water, adjusted to the suspended solids load.
• Oxygen scavengers: Set on the dissolved oxygen in the feed water, dosed after the deaerator.
• Alkalinity builders: 5–20 ppm in feed water, adjusted to hold boiler water pH in the recommended band.
• Condensate treatment: Set on the condensate pH and CO₂ load.

These are starting ranges. The working dose is confirmed from your water analysis and the TDS for the product, and it is adjusted through the year as the feed water quality changes. Our team reviews the dosing plan with your boiler engineer before the first charge.

Packing

• 35 kg HDPE carboys for liquid grades (standard)
• 200 L HDPE drums for liquid grades

Standard industrial packing; pack sizes on request.

Support from Water Analysis to First Charge

For industrial boilers in Nepal — sugar mills, cogeneration units, pharmaceutical and food processing plants — we review your feed water and boiler water analysis, go through the product selection with your boiler engineer, and review the dosing plan before the first charge. If boiler water pH, dissolved oxygen or condensate pH starts drifting, call us — we will look at the operating data with you. TDS is shared on request.

Frequently Asked Questions

Which boiler water treatment chemicals does Innovacorp make for Nepal plants?

Innovacorp manufactures scale inhibitors, sludge conditioners, oxygen scavengers, alkalinity builders and condensate treatment chemicals for industrial boilers in Nepal. The product mix is set after a feed water and boiler water analysis, not on a fixed package.

How is the boiler water treatment programme set for a Nepal plant?

The programme is set on the feed water and boiler water analysis — hardness, alkalinity, dissolved oxygen and conductivity — along with the boiler pressure and blowdown practice. We review your analysis, go through the product selection with your boiler engineer, and confirm the dose before the first charge.

What is the typical dose of boiler water treatment chemicals?

Dose depends on feed water quality, boiler pressure and blowdown practice. A typical starting range is 5–50 ppm of active chemical in the boiler water, adjusted after a baseline water analysis. Scale inhibitors and sludge conditioners sit at the lower end; oxygen scavengers and alkalinity builders are set against the dissolved oxygen and pH targets for your pressure band.

How should boiler water treatment chemicals be stored at a Nepal plant?

Store in the original container, in a cool, dry, ventilated area away from direct sunlight and incompatible chemicals. Keep the lid tight when not in use and follow the handling guidance on the TDS. Do not mix with other chemicals in the storage area.
