10 tons of boilers need energy efficiency test

Furnaces and Boilers | Department of Energy

Energy efficiency upgrades and a new high-efficiency heating system can often cut your fuel bills and your furnace's pollution output in half. Upgrading your furnace or boiler from 56% to 90% efficiency in an average cold-climate house will save 1.5 tons of carbon dioxide emissions each year if you heat with gas, or 2.5 tons if you heat with oil.

Q1: What is the boiler efficiency?

1 Annual Fuel Utilization Efficiency, as determined in section 10 CFR 430.23(n)(2). (NOTE: The CFR refers to 10 CFR 430.22(n)(3), which is a misprint. The correct section is 10 CFR 430.23(n)(2) as listed above.) A boiler that is manufactured to operate without any need for electricity or any electric connection, electric gauges, electric pumps, electric wires, or electric devices is not

Energy Efficiency Opportunities in EPA's Boiler Rules

with boilers that burn only natural gas, the rule may not apply or can be met though energy efficiency practices. Residential boilers and hot water heaters are not covered by the rule. The rule has different requirements for large facilities, known as Major Sources, and smaller facilities, called Area Sources. Major Sources are sites that emit (or have the potential to emit) 10 tons per year of an individual HAP

Applicable to small coal-fired boilers < 10 MMBtu/hr, all biomass-fired boilers, and all oil-fired boilers. Rationale by improving combustion efficiency, fuel usage is reduced which results in decreased emissions. Energy Assessment Applicable to existing large boilers > 10 MMBtu/hr, except limited use boilers (with a federally enforceable
