Boiler System Efficiency

Journal

When natural gas cost $0.40 per therm* (1999), even a poorly designed boiler system would have positive payback. Hurricane Katrina changed that. According to the Energy Information Administration (www.iea.doe.gov), the cost of natural gas has increased 50% in the U.S. since last fall (due to Hurricane Katrina) and 200% in the last seven years. Electricity has increased only 20% in the same time frame (central Indiana). Winter 2006 natural gas cost as much as $1.40 per therm (100,000 Btu) and electricity costs around $0.07/kWh (3,413 Btu). The electric cost equates to $2.05 per therm.

Engineers Notebook: Design Tips to Avoid Boiler Short-Cycling

Journal

Boiler short-cycling causes excessive wear and tear on the boiler and has a tremendous penalty on boiler efficiency. Kent provides tips to help designers improve heating hot water system performance.

Dual, dissimilar boiler flame safety controls

Journal

Describes how a building management agency operating multiple plants in new Jersey resolved a boiler plant staffing problem for 34 low-pressure steam fire-tube boilers ranging from 2,453 kW to 4,905 kW (250 to 500 boiler hp) by implementing an approved programme for operation, monitoring and documentation for 14 boiler plants. The boilers were retrofitted with a dual, dissimilar flame safeguard control system with remote monitoring and a dissimilar low-water cut off on each boiler. Describes the systems, their installation and remote monitoring system. Notes their satisfactory operation and a payback period of less than one year.

Five Design Factors to Help Optimize a Boiler Plant

Journal

Engineers designing boiler plants need heat and hot water solutions that save installation time, lower construction costs and deliver superior performance. This article discusses five factors to consider: the plant’s function, piping design, boiler selection, boiler controller and remote access.

Understanding Fuel Savings in the Boiler Room

Journal

As oil prices hit record price levels, building owners and facility managers seek to better understand boiler efficiency and how to save on fuel costs. When operated at a 25% capacity factor, a boiler annually consumes four times of its capital cost in energy. Burner and combustion control retrofits offer owners the quickest paybacks based on energy savings. This article explains how to better understand the effect of burner and controls performance on efficiency, boiler heat losses, and saving fuel with multiple boiler plants.
