Can effective combustion control reduce emissions by 10% each year?

April 23, 20192:41 pm
At Energy Technology & Control we’re confident that effective combustion control can reduce emissions by up to 10% each year, saving industrial burner operators thousands in energy costs. Our combustion control specialists explain how… The facts Typically, combustion of 1m3 of Natural gas in an industrial boiler produces 2.03kg of C02, and 1 kWh of electricity generated in a gas fired power station produces 0.420kg of C02. It is not unusual for an industrial burner/boiler to use in excess of 130,000 pounds of fuel per annum, directly emitting up to 15,700 tonnes of C02. If we add to that figure, the electricity used to power the burner fan, then the total C02 emissions caused by a single burner of this size can exceed 15,750 tonnes per annum. From an environmental perspective it obviously makes sense to aim for a reduction in CO2 emissions, there is however also a business case for this as reduced CO2 is usually a result of improved efficiency and fuel consumption. The solution Electronic controllers ETC’s electronic combustion controllers are usually customised for each burner manufacturer. This ensures that the unique design features of each burner are fully realised. Integration of burner and boiler control into a small electronic controller removes the need for large cabinets or housing; this lowers capital cost and in turn improves space utilisation. When using an electronic controller, the low fire point can be set lower than the ignition point meaning that the turn-down ratio can be increased and burner on/off cycles and their associated cold air purges reduced. Savings of 5% have been reported on a burner that prior to conversion had an on/off frequency of approximately once every 10 minutes. If a plant does not run continuously then a second modulation control setpoint can be used to switch the boiler to a lower steam pressure or hot water temperature during periods of reduced activity. Oxygen trim When oxygen trim is employed oxygen levels can be trimmed to their optimum level. This process automatically and continuously compensates for the variables that affect efficient combustion. An adaptive trim system will contribute energy savings of approximately 3% per annum. Air dampers Unfortunately air dampers can leak and even when fully closed the air flow can be significant. However combustion efficiency can be improved at low fire if the fan speed is reduced. By simply adding fan speed control, burner turn-down can be…

Celebrating 30 years of worldwide success

February 7, 20192:49 pm
Energy Technology & Control has been a global leader in the design and development of combustion controls and burner control technology for an impressive 30 years. To mark the occasion, ETC has created an infographic outlining some of the most notable dates in the company’s history. It is fitting that the first date of interest should be the date of the management buyout in 1988. The next decade was a busy one as ETC started to build its reputation and gain traction in the electronic burner controls market, firstly securing European approval for the ETC3000 electronic air fuel ratio controller, before launching it in the UK market a year later. In 1998 the ETC3000 electronic air fuel ratio controller received USA, UL and FM approval allowing ETC to enter the US market represented by Fireye Inc. In the same year the company were thrilled to receive the highest official UK award for British business – the Queen’s Award for Environmental Achievement – for the combined combustion of base and waste fuels offered by the ETC3900 burner control. The 90s ended on a high with approval received for ETC’s first fully integrated burner control system, the ETC1200, in 1999. The millennium saw ETC set its sights on the world stage; in 2000 the ETC3000 burner control received Australian AGA approval, allowing ETC to market its products on the other side of the world. In 2006 the ETC6000 burner management system was launched – quickly receiving European approval – and leading to ETC’s first project with HP-Consulting in Germany in the following year. In 2008 the ETC6000 series burner management system received UL, FM and AGA approval. This led to partnerships being established with; Italian company General Bruciatori in 2008, Spanish company E&M Combustion and Czech company PBS Power Equipment in 2009, the following year ETC agreed partnerships with Hamworthy Combustion in France and Gastech-Energi in Denmark, finishing 2010 in a strong position with its burner controls and burner management systems being fitted throughout Europe and beyond. In 2011 ETC strengthened its position in Italy securing a second partnership with Italian OEM Bono Energia. The company also added two new models – the ETC6008 and ETC6009 – to the established ETC6000 series burner management system range of combustion controls. The ETC6008 & ETC6009 are designed to address applications where bio and waste fuels are being used. The year closed on a high…

Industrial burner controls

February 7, 20192:43 pm
How using electronic burner controls can significantly reduce costs Energy costs in many of the industries that employ process heating are considerable. Negotiating a good fuel and electricity price can help to keep energy costs under control. But is your burner controls set up working as hard as it should be? Our industrial burner control experts examine the money saving solutions available in the UK. Control is key Controls for industrial burners have changed significantly in recent years; mechanical cam fuel:air ratio control has been replaced by self-checking fuel:air ratio electronic control. Oxygen trim has been added with flue gas re-circulation working to reduce emissions. Performance has been improved by increasing turn down ratios through more flexible control strategies and fan speed control, as well as by improved matching of load and demand from embedded 3 term PID systems. Software options such as boiler lead/lag control can improve burner utilisation and communications software can greatly enhance information flow. Most of the improvements to industrial burner controls have been introduced in the last few years. These controls can be specified on new burners or retrofitted to existing plant. It is now possible to reduce energy costs to lower emissions and to obtain trending information for management decisions. Self-checking controls with automatic logging and dial-out can release boiler house manpower for other process applications. If you haven’t reviewed your industrial burner controls in the past five years, make 2019 the year that you take action. Mechanical cams and linkages – is your boiler really as efficient as you think? Consider a typical industrial boiler with mechanical cam control and let us assume that the burner has recently been serviced. At high fire, the oxygen level in the flue gas would have been set at a safe level – slightly above optimum – to allow for changes in conditions that affect combustion. When burning oil, viscosity, calorific value and filter condition will all cause variations in combustion and when firing on gas the supply pressure and calorific value of the gas will both cause variations in combustion. The burner engineer will make allowances for any backlash in the linkages associated with the cam and will set the cam to ensure that the oxygen cannot fall too low. After all, if the oxygen level in the flue gas is too low the risk of explosion is increased. In addition the risk of emissions containing…

ETC Launches Combustion Controls for Waste Fuel Firing

August 22, 20182:52 pm
Energy Technology & Control Ltd, a UK manufacturer of electronic Burner Management Systems, has expanded its range of combustion controllers to allow waste and bio-fuels to be fired either independently or simultaneously with a conventional gaseous or liquid base fuel. Simultaneous firing of fuels can usually be achieved using conventional products but waste and bio-fuels are often characterised by variable availability and inconsistent calorific values. To overcome this an algorithm within the controller software enables safe and efficient combustion to be achieved; an external signal is used to indicate the proportion of waste fuel that should be used across the firing range. Oxygen trim ensures that any variability in either the fuel calorific value or external atmospheric conditions does not compromise combustion efficiency. ETC6008_ETC6009_Waste_&_Biofuel ETC6008 and ETC6009 and waste fuels The ETC6008 caters for liquid and gaseous fuels to be fired either independently or simultaneously. A second new model the ETC6009, is designed to allow a gaseous base fuel to be mixed with a gaseous bio or waste fuel and includes the provision for valve proving on two separate gas trains. The ETC6009 can be further enhanced to facilitate the firing of a back-up liquid fuel. The full range of ETC peripherals including a 10.4” touchscreen, CANbus servo motors, and temperature and pressure sensors are all fully compatible will all the new models.
