Eastern Michigan University (EMU) is located in Ypsilanti, Michigan, approximately 35 miles west of Detroit and 8 miles east of Ann Arbor. It was founded in 1849 as a small teachers college and today has grown into a major public learning and research institution with over 21,000 students. EMU historically has been a leader in energy efficiency and sustainability. In 1987, the University ...
Meanwhile, Kemco’s stack economizer can safely reduce gases as low as 40°F.Why Choose Kemco System’s Stack Economizer (Solution) Kemco’s stack economizer is designed to be an energy savings solution recovering heat that would otherwise be lost from boiler stacks. Typical gas-fired boilers lose 20% or more of consumed energy from their exhaust. ...
Because of this, Operators Unlimited implemented customized treatment plans for both the boilers and the cooling towers.Implementing Boiler Treatment Plan Reducing Corrosive Dissolved Oxygen Normal deaerator operations produce less than 10 ppb of dissolved oxygen in boiler feedwater. Still, even miniscule quantities of dissolved oxygen can be ...
For example, a critical issue in the power industry is steam surface condenser performance, in which the condenser, as its name implies, converts turbine exhaust steam into condensate for return to the boiler. This process improves the thermodynamic efficiency of the Rankine cycle by nearly one-third over what it would be if the steam were not condensed. ...
Cost savings were another driver: the campus needed to replace two aging boilers (of 1960s vintage) that supplied hot water to heat campus buildings, and the university calculated that upgrading to CHP instead of just replacing the old boilers would provide good economic returns in the long run. ...
Steam boilers are vessels to which heat is applied so that water is continuously converted in to steam. ‘Feed water’ is the water added to a boiler to replace that lost due to evaporation and blow down. Often steam is condensed and returned to the boiler as part of the feed water. ...
Before deciding to apply insulation to condensate handling/ boiler feed equipment, however, you should address issues that have been raised in site visits and comments from the field. Adding insulation may not be the money-saver it appears Insulation is typically applied to retain latent heat from the condensed steam and minimize the energy needed to create new steam in the ...
Other systems cool down steam that hasn’t been used in steam turbines, for example, condensing vapour into liquid again before re-feeding it into the boiler. When there is little steam to be returned to the condenser, less seawater is required, enabling the speed of the pump to be reduced to a necessary minimum. ...
Project - Steam Boiler Water Pre-Heating Faced with increasing energy costs this major mushroom production processor initiated a fundamental expenditure review. Rising energy costs quickly highlighted the three process boilers used to supply steam into the production process. After an extensive feasibility study three Econotherm® gas to water (GW) units were ...
The boiler tube failures were a result of the incoming water quality to the power plant. Until recently, the boiler make-up water was treated with a combination of carbon media filtration and softening. As a result less than 50% of condensate was returned and the power boiler ran at 7 feed water cycles. A local Culligan dealer ...

Thermal Energy International demonstrated that by replacing the existing traps with the GEM venturi orifice design, blocked steam traps could be prevented from impacting on production and start-up times, and by efficiently returning condensate back to the boilers maximum energy savings would be achieved. ...
Thermal Energy International explained that by replacing the existing traps with the GEM venturi orifice design, blocked steam traps could be prevented from impacting on production, and by efficiently returning condensate back to the boilers energy savings would be achieved. ...
As the traps were not regularly inspected, it was often sometime before it was found that the mechanical traps was not working, by which time the failed open steam traps were impacting on steam production by not returning condensate back to the boiler. This was costing the company 250 euros a month for each failed steam trap. ...
They have the experience and expertise to advise about every aspect of reducing energy costs and carbon emissions from boilers, condensate return systems, dryers and heat exchangers. Companies such as Thermal Energy International offer a complete package of expert engineering services, analysing different options required to meet customer’s needs, fully ...

TEI explained that by replacing the existing traps with the GEM venturi orifice design, steam traps would be prevented from blocking and impacting on production and by efficiently returning condensate back to the boilers energy saving would be made. A total of 71 mechanical traps were replaced with appropriately sized GEM steam traps. ...
As the traps were not regularly inspected, it was often sometime before it was found that the mechanical traps had failed, by which time the blocked steam traps were impacting on steam production by not returning condensate back to the boiler. Having struggled to find a steam trap that would work successfully, Managing Director, Jonathan Cross looked around for ...
Once purified, the water is used as feed to the boiler for generation of Steam for injection into the formation and the cycle continues. ...
It is often thought that existing building management systems (BMS) and building energy management systems (BEMS) are optimising the boilers to remove dry cycling. However, the BMS is optimising the building not the individual boilers…The system should therefore be optimised through intelligent analysis of each gas boiler’s flow and ...
Installing gas boiler load optimisation controls can reduce this waste and help boilers run more efficientlyBuilding engineers, energy and facilities managers tend to overlook that many gas boilers waste energy through dry cycling when they are not actively contributing to the building heating and hot water demand. ...
