Steam jet heater

Introduction:

 

Steam jet heater is used to raise the temperature of water or other liquids by mixing with directly injected heating steam. It is efficient heating equipment for corrosive liquids, sewage water, underground water, untreated water, etc. Steam heat heater has got successful applications in chemical plant, power plant, wastewater treatment, underground water heating, chemical fertilizer production, textile industry, paper mill, etc.

Principle:

 

Steam jet travelling at high speed creates a negative pressure, which sucks surrounding water at the outlet. Water is entrained with steam and moves forward. Steam condensate mixes with liquids being heated. Water circulation caused by steam jet heater would ensure sufficient mixing. If necessary, air or inert gas could be introduced to make heating faster and more silent.

 

Features:

 

1. Especially suitable for heating of corrosive and abrasive solution or slurry.

2. Low vibration, low noise.

3. 100 percent heat utilization.

4. Difficult to be clogged, uniform mixing, fast heating.

5. Simple structure, long service life, maintenance free.

6. Temperature raise up to 70℃.

 

Application:

 

1. Steam/water heat exchange station in central district heating.

2. Bathroom, washroom water heating.

3. Thermal preservation, heat tracing and washing of equipment in chemical industry.

4. Substitutes for high/low pressure heater, desalted water heater in power plant.

5. Mixing of sizing agent in paper making.

6. Mixing & heating equipment in pharmacy, food, dying industry.

7. Energy recovery from deaerator vent.

8. Energy recovery from exhaust steam in chemical, oil industry.
