High Pressure Boiler vs Low Pressure Boiler in Sugar Mill
In a low-pressure boiler the pressure does not exceed 15 psi, and hot water heating boilers are not designed to exceed over 260 psig. While high-pressure boilers will heat steam above 15 psi and water at pressures that exceed 160 psig. Temperatures in high-pressure boilers will exceed 250 degrees F. High-pressure boilers are used in industries and designed to generate the steam found in sugar mill, power plants, textile industry, paper plant, chemical industry, rice mill, etc.
Variable that affects boiler pressure:
1) Fuel
Different fuel have different energy content and different flame temperature. Some traNsfers energy differently like though radiant heat. It also depends on how much you can feed into furnace and into what furnace geometry. You can even boil water using waste heat and solar power.
2) Boiler area- The higher the area, the higher the heat flux
4) Boiler configuration - with superheater? with economizer? fire tube or water-tube? etc
5) Material and thickness - temperature and pressure affect tube integrity
6) Downstream requirement - Smaller locomotive tonnage do not require a such a high pressure.
ZBG can supply both low pressure boilers for sugar plant steam need and high pressure boiler for its captive power plant. If you have interested in the sugar plant boilers no matter high pressure or low pressure, we'll be happly to provide help!
