Detergent Powder Hot Air Furnace — Kenya

Special Hot Air Furnace for Detergent Powder Production in Kenya

Meibao supplied a special hot air furnace for a detergent powder production project in Kenya.

 

The furnace uses coal or biomass as its fuel configuration and integrates fuel combustion, high-temperature purification, dust settlement, cold-air mixing and temperature control. It provides 350–450°C process hot air for the detergent powder spray-drying tower.

The hot air furnace is designed specifically for the drying requirements of detergent powder production.

Fuel burns inside the combustion unit and generates high-temperature gas. The gas enters the high-temperature purification chamber, where entrained dust agglomerates and settles.

The purified hot air leaves the purification chamber at approximately 900°C. A controlled quantity of cold air is then introduced into the mixing chamber, reducing the temperature to the 350–450°C range required by the detergent powder spray-drying process.

The adjusted hot air is delivered through the hot-air duct to the spray-drying tower, where it provides the heat required to dry the atomized detergent slurry.

Biomass is transferred through the fuel-feeding system to the combustion unit. The combustion process generates high-temperature gas, which enters the high-temperature purification chamber.

Dust carried by the combustion gas is removed and settled inside the purification section. The resulting clean hot air is controlled within a temperature range of 550–700°C.

Circulation fans deliver the hot air to the rubber drying oven and distribute it through the drying chambers. The hot-air circulation system supports continuous and controlled rubber drying.

1. Fuel Feeding

Coal or biomass is transferred to the combustion unit through the corresponding fuel-feeding system.

The fuel supply is coordinated with the required hot-air temperature and heat demand of the spray-drying process.

2. Fuel Combustion

The fuel burns in the combustion unit and generates high-temperature gas.

The combustion system provides the heat required for continuous detergent powder drying.

3. High-Temperature Purification

The high-temperature gas enters the purification chamber after leaving the combustion section.

A small quantity of dust carried by the gas agglomerates and settles inside the chamber. This process reduces the amount of entrained particulate matter before the hot air enters the mixing and drying sections.

4. Purified Hot-Air Output

The purified hot air leaves the high-temperature purification chamber at approximately 900°C.

The combustion and purification sections are designed as an integrated furnace system.

5. Cold-Air Mixing

Controlled cold air is introduced into the mixing chamber and combined with the purified high-temperature hot air.

The final process hot-air temperature is adjusted to 350–450°C according to the spray-drying requirements.

6. Spray-Drying Tower Connection

The adjusted hot air is transferred through the duct system to the detergent powder spray-drying tower.

Inside the tower, the hot air contacts the atomized detergent slurry and provides the heat needed for moisture evaporation and powder formation.

7. Temperature and Heat-Supply Control

The control system coordinates fuel feeding, combustion, air supply and hot-air temperature.

The continuous hot-air temperature stability is maintained within ±5°C.

Designed for Detergent Powder Drying

The combustion, purification and mixing sections are configured around the hot-air requirements of a detergent powder spray-drying tower.

High-Temperature Purification

Dust carried by the combustion gas agglomerates and settles inside the purification chamber before the hot air enters the drying system.

Adjustable Process Temperature

Cold-air mixing controls the spray-drying hot-air temperature within the 350–450°C range.

Temperature Stability

The continuous hot-air supply maintains a temperature stability of ±5°C.

Direct-Fired Heat Utilization

The purified hot air is used directly in the spray-drying process after temperature adjustment. The furnace series is designed with a thermal efficiency above 95%.

Coal and Biomass Configurations

The furnace series can be configured for coal or biomass according to the selected fuel system.

The special hot air furnace series is suitable for drying:

• Detergent powder
• K12 / sodium lauryl sulfate
• AOS surfactant products
• Detergent additives
• Other powder products using compatible spray-drying processes

These applications describe the furnace series and do not represent all products manufactured at the Kenya project.

The special hot air furnace for detergent powder production incorporates multiple patented technologies.

Its structure combines fuel combustion, high-temperature purification, dust settlement, cold-air mixing and temperature control to provide process hot air for detergent spray drying.
