Biogas from Landfills in cogeneration power plants
Solid wastes from households, commercial and industrial activities enter a landfill, where methanogen bacteria decompose the organic material. The by-product of the bacterial decomposition is biogas composing from anywhere between 30-50% carbon dioxide and the remainder methane gas. In order to collect this gas, a series of pipes are embedded within the landfill and is compressed and mixed with natural gas as fuel for power generation. Landfill gas is very humid, at low pressure (20-40 mBarg) and about 40-60°C (100°F). Measuring the biogas as it leaves the landfill is difficult because it is dirty and having very low pressures. Low pressure makes differential pressure (DP) devices like orifice plates unsuitable since they require a fairly large differential pressure to operate. Moreover high moisture and particulate content can clog up devices like annubars and orifice plates and gum up turbine meters and similar instruments that have moving parts. The SmartMeasurement™ ATMF thermal mass flow metes, with no moving parts to clog with dirty, particulate laden gas and a self-cleaning purge option for dirty flow environments, the ATMF thermal mass flow metes maintains accuracy and lowers maintenance costs. The ATMF thermal mass flow metes sensors automatically corrects for changes in gas temperature and pressure, eliminating the need for separate temperature and pressure transducers.

• The SmartMeasurement™ ATMF biogas mass flow meters, with its no moving parts and wide turn-downs, low pressure drops are ideal for cogeneration power plants. Further blending with natural gas necessitates the use of ATMF mass flow meters for blending optimization.
• The SmartMeasurement™ ALVT vortex flow meters are an ideal choice to measuring and control steam boilers in the cogeneration power industries.
Geothermal Power plant
Geothermal resources have been used as source for cooking and heating. Today, geothermal power plants are producing over 8,200 megawatts of electricity that supplies over 60 million people in 21 countries. In a typical steam field, the geothermal reservoir rock consists of fractured greywacke and greenstone heated to a temperature of 460-480°F (237-250°C). The fractures are filled with superheated steam at pressures that, depending on location, can vary from 100 to 240 psig (7-16.5 Barg). This superheated steam is collected at the wellheads and sent to an electrical generating station that consists of a heat exchanger and a turbine and generator set. Steam is typically delivered to the turbine at 70 psia and 300°F to 350°F, at a flow rate of approximately 890,000 lb. /hr. (400,000Kg/hr.) at maximum capacity. Because of high temperatures and varying pressures, measuring steam flow is with a volumetric flow meter is not accurate. More over volumetric flow meters are particularly sensitive to the formation of scaling and plugging. The best known solution to measure steam flow in this application is the SmartMeasurement™’s ALVT-Mass vortex flow meters with integral temperature and pressure compensation. The ALVT-Mass vortex flow meter improves accuracy and reliability with lower installed costs because there is no need to also install pressure and temperature devices as required with volumetric flow meters. Moreover the relatively small surface area of the ALVT-Mass vortex flow meters insertion style in big pipes eliminates the large pressure drop associated other flow meters. The ALVT-Mass vortex flow meter sensors small surface area also equalizes quickly with the surrounding steam temperature, thereby eliminating scaling due to temperature differentials.

Solar thermal energy (STE) plants
The solar collector comprised of a huge array of concave mirrors. These mirrors track the position of the sun throughout the day, focusing the sun’s energy on a black tube that runs along the focus of the array. This black tube is surrounded by a second glass tube vacuum chamber that protects it from the air, allowing it to absorb solar energy more effectively. As super-heated water passes through the black tube, the solar energy heats it up to 450°F (232°C). Hot water is measured by the high temperature ALVT vortex flow meters, while steam and condensate flow can be measured by the ALVT-Mass vortex flow meter in the system. The water then runs through a boiler system that uses its heat to generate steam. The steam can used to generate electricity or in certain manufacturing process, it is also used to transfer heat to other process like oils or other fluids. Cooled water flows back through the tube to the solar concentrator field will be measured by the ALMAGWP electromagnetic flow meters and the process is repeated.

Flue Gas Balancing
Combustion exhaust gas (flue gas), which contains by-products harmful to the environment must be cleaned before release to the atmosphere. When fly ash-laden flue gas flows from one or more boilers to multiple scrubber modules, a serious problem arises in balancing the flow to the modules so that each operates at its maximum efficiency. Poor scrubber performance not only increases the mass flow of pollutant to the atmosphere, but also clogs mist eliminators or re-heaters and causes corrosive damage to downstream components. Often times Pitot tubes, annubars or Venturi meters are used to monitor the mass flow which must have a pressure, temperature sensors as well as a flow computer. Build-up in these meters will alter the pressure drop as much as changes in flow. Since these devises are DP type instruments, power plant personnel has no reliable way of knowing how much flue gas is flowing in each scrubber module because changes in pressure are used to infer flow rates in these devices. The SmartMeasurement™ ATMF air mass flow meters outfitted with a shield to guard against build-up, will provide consistent and reliable mass flow data.
