What to Know About High-Efficiency Furnaces | Hunker

Jan 21, 2019· High-efficiency furnaces and boilers have a second heat exchanger that captures most of the heat standard furnaces waste. When you are replacing an older furnace or if you are choosing a furnace or boiler for new construction, you are likely to be faced with a choice between a mid-efficiency "regular" heating unit and a high-efficiency one.

Furnace - Sulphuric Acid

The sulphur furnace should be sized for the approximately 0.094 m³/tonne (3 ftª/ton) per day of acid production based on a maximum gas strength of 12% SO2 and a plant located at sea level. For a 2000 tonne per day acid plant, the furnace volume required is 188 m3 (6639 ft3) minimum.

Corrosion in boilers - Lenntech

Corrosion is a relevant problem caused by water in boilers. Corrosion can be of widely varying origin and nature due to the action of dissolved oxygen, to corrosion currents set up as a result of heterogeneities on metal surfaces, or to the iron being directly attacked by the water.

high-efficiency furnace: water discharge; Author: Anonymous User We just replaced our 60-year-old home's 1970s furnace with a 93/high-efficiency one. I was surprised by the water discharge--but I now understand how/why it's produced. A corner of my home's basement had a sump pump pit (about 18" square) installed in the 60s.

Steam, produced in the furnace waste-heat boilers, is used to drive the acid plant blowers that move the gases through the plant. Excess heat from the reactions on-going in the acid plant is used to generate low pressure steam which is blended with the residual steam from the blowers and directed to a turbo-generator at the powerhouse.
