  • Sulfur Heating Oil and Condensing Appliances
    IMPROVED EFFICIENCY AND EMISSIONS WITH LOW- SULFUR HEATING OIL AND CONDENSING APPLIANCES Wai-Lin Litzke, Dr. Thomas Butcher and Roger McDonald ABSTRACT High levels of fine particulate matter (PM2.5) in NYC and surrounding metropolitan areas have been attributed mostly to diesel engines with contributions from oil used for heating during the wintertime. No. 2 heating oil consumption, typically high-sulfur, is concentrated in the Northeast region with about 3.4 billion gallons (1997 data) used annually in the Mid-Atlantic states (NJ, NY and PA). Improved energy efficiency of furnaces and boilers with significant reductions in sulfur oxides and total particulate matter can be achieved through the use of low-sulfur fuels. Reducing sulfur levels even further to ultra-low levels, which is now available as transportation diesel, allows for continued advances in condensing oil-fired systems. These advances allow for up to 10% improvements in energy efficiency or 94% efficient systems. Brookhaven National Laboratory is developing these technologies with the objectives of quantifying the efficiency benefits in addition to characterization of emissions. These new technologies offer significant energy benefits but it is not known what their impacts will be on particulate emissions. For example, in the case of condensing boilers do these systems provide an opportunity to capture some of the particles on wet surfaces before being emitted? This poster will present specific data on the correlation between sulfur levels and PM2.5 using a new, portable dilution tunnel sampling system for condensing boilers and furnaces in residential systems.

The Library is published in five chapters, each containing control strategies relating to the following main types of plant: · Chapter 1: BMS plant start /stop signals · Chapter 2: Heating systems · Chapter 3: Air handling plant · Chapter 4: Pumping · Chapter 5: Cooling systems In each chapter the control of the principal plant items in current use are described. Where there are many plant items which carry out the same function but using different techniques, for example, water heating, the modular format of the Library allows a ‘pick and mix’ selection of plant modules to be made to provide the required configuration of a complete system. Each plant module is shown in the form of a schematic and is described in terms of its general function and how it is controlled.

The plant is devoted to covering the domestic hot water and space heating demands of a district composed of six typical residential buildings located in Naples (southern Italy). Three alternative natural gas-fueled back-up auxiliary systems (condensing boiler and two different technologies of micro-cogeneration) aiming at balancing the solar energy intermittency are investigated. The utilization of electric storages in combination with the cogeneration systems is also considered with the aim of improving the self-consumption of cogenerated electric energy; heat recovery from the distribution circuit is also evaluated to pre-heat the mains water for domestic hot water production. The performances of the proposed plant schemes are contrasted with those of a typical Italian decentralized heating plant (based on the utilization of natural gas-fueled non-condensing boilers).

Pages 10 / 11 Heating with hydrogen – innovative technology for a climate-neutral future The first gas condensing boilers and fuel cells certified to run with blends of up to 20 percent hydrogen will be coming onto the market in 2021. This makes Viessmann a leading innovator in the use of hydrogen to generate heat and power. Pages 12 / 13 New generation of heat pumps with high flow temperature With a flow temperature of up to 70 °C, Vitocal 25x-A was developed with modernisation projects in mind. You can continue using any existing radiators. With its extremely low GWP (Global Warming Potential) value of 3, the "green" refrigerant R290 (propane) these units use is especially environmentally responsible.

  • Condensing Boilers for Existing Buildings Opportunities and Pitfalls by Brian O’Donnell
    technology condensing boilers for Existing buildings opportunities and Pitfalls By BRian o’Donnell ith maximum efficiency ratings in the range of 96 per cent, condensing boilers are becoming a popular choice for building Wowners looking for improved energy efficiency, reduced operat- ing cost and lower GHG emissions. However, many owners are not aware of the technology behind condensing boilers and the conditions required for achieving their rated efficiency. Mismatching the boiler with the heating system requirements can result in operating conditions that do not achieve the potential of condensing boilers. The high efficiency rating for condensing boilers is primarily achieved by capturing latent heat from water vapour in the flue gas. This is done by con- densing, or changing the phase of water vapour from a gas to a liquid. As the water vapour in the flue gas condenses, it releases heat that is then cap- tured in a heat exchanger and transferred to the boiler return water flowing through the other side of the heat exchanger. For this process to occur, the return water temperature has to be below the dew point of the water vapour. The dew point for natural gas combustion products is typically around 55°C (130°F) under Stoichiometric conditions. To obtain complete con- densing and achieve the maximum rated efficiency of the boiler, return water temperature needs to be approximately 20°C (68°F), which is extremely low and unachievable for most applications. Between return water temperatures of 20 to 55°C, condensing will partially occur but the boiler does not reach the maximum rated efficiency.
