Sacramento Airport Installs AM Inverters Harness Solar energy Sacramento International Airport (SMF) has installed a photovoltaic (PV) system to harness solar energy in an effort to advance its sustainability. Solar technology company SMA has provided the photovoltaics to the US airport. The 7.9 MW project, using SMA’s inverters, has been implemented across a 15-acre land parcel near the airport’s economy parking lot, as well as a 20-acre location north of the runway. The solar power facility uses two Sunny Central 2200-US inverters, which are integrated with a medium-voltage block, in addition to three Sunny Central 800 CP-US inverters. SMA America general manager Jim Crossen said: “We are pleased to partner with Borrego Solar to bring renewable energy to the Sacramento International Airport, which holds special meaning because our US headquarters is located in the Sacramento region. “With Sunny Central inverters delivering reliable, robust performance, we are confid...

Electrical Vehicles are the near future of automobile sector, automobile manufacturers are planning hundreds  of models for EVs Electric cars comprise only 1% o automobile sector globally. In future, nobody knows what will be the actual demand for electric cars. Fords and Volkswagen are one of those planning many models o EVs in China Energy and mobility are the pillars of social transformation. As the urbanization increases cities will under significant transformation, so the policymakers and industry leaders have to get ready for the transformation. Electric mobility is widely seen today as the way to improve air quality and meet climate goals and should be integrated into the comprehensive vision of smart cities. chinese cities are famously polluted, air pollution is  the cause of millions of deaths in China china succeeded in increasing the air quality in some cities by shifting polluted factories away from...

Keep an optimal excess air level, generally, about 20% in a coal-fired boiler Tune combustion of coal to the optimal condition. Understand the coal being fired Proper distribution of combustion air at primary, secondary, and tertiary levels Keep the required fineness of coal about 75% through 200 mesh and less than 2% on 50 mesh sieve Keep the maximum mill outlet temperature to reduce air bypassing air pre-heater Soot blowing the entire heat transfer surface at an optimal frequency Minimize the air in leakage to the boiler Dry gas loss is also influenced by the economizer feed water inlet temperature and the ambient air temperature, which change the heat recovery pattern of economiser & air-pre-heater.

PARAMETERS REQUIRED TO BE MAINTAINED STRICTLY  FOR EFFICIENT OPERATION OF AFBC BOILERS — Bed Height/FD Air Pressure — Primary Air Pressure — Bed Temp./Furnace Temperature — Fuel Size — Bed Material size & Specifications — Air & Fuel ratio — BED HEIGHT/FD AIR PRESSURE — Static   height for AFBC Boiler is to be maintained 300 to 325 mm during initial light up of boiler. — Expand bed height for AFBC boiler is to be maintained 500 mmwc to 600 mmwc. — FD Air discharge Pressure is to be maintained 600 to 650 mmwc. — Wind box or Air Box pressure is to be maintained 500 to 600 mmwc. NOTE: High W.B. pressure increases the erosion of bed coils & low W.B. stops fluidization. PRIMARY AIR PRESSURE — P.A. fan air header pressure for AFBC boiler is to be maintained 1000 to 1150 mmwc. — Difference of primary air pressure & F.D. wind box pressure is to be maintained approximately 500 mmwc. NOTE: High P.A. pressure increases the b...
