Abstract
Technology is now available to increase heater efficiencies to 92 percent and more. By 1980, this technology will be field proven and corrosion and reliability problems identified and resolved.
Recent studies have shown that a minimum efficiency of 92 percent can be justified on heaters as small as 5 MMBtu/hr. with payouts below 3 years using $2.50/MMBtu fuel costs. Fuel costs continue to rise and many companies feel that $4 to $5 per MMBtu values are only a few years away.
