cogeneration plant is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
Technical advantages Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
Cogeneration describes the simultaneous production of electricity and thermal energy using a single fuel source. Cogeneration, or cogen for short, also called Combined Heat and Power (CHP), consists of a number of components including a prime mover, generator, heat recovery system, and thermal distribution system.
Combined heat and power (CHP) cogeneration. One solution is to swap some of our power plants over to a different system called combined heat and power (CHP), also known as cogeneration. CHP plants make better use of the fuel we put into them, saving something like 15–40 percent of the energy in total.
What Is Cogeneration Cogeneration (Combined Heat and Power or CHP) is the simultaneous production of electricity and heat, both of which are used. Cogeneration therefore offers energy savings ranging between 15-40% when compared against the supply of electricity and heat from conventional power stations and boilers.
Through rigorous analysis and broad consultation with leading experts, the Capitol Power Plant has identified cogeneration as the preferred solution for our energy future. Completed in 2018. The Capitol Power Plant's cogeneration system will use natural gas in a combustion turbine to generate electricity and heat, increasing system reliability, improving efficiency and saving taxpayer dollars.
Cogeneration plants, also known as combined heat and power plants, burst onto the power generation scene in a big way during the Public Utility Regulatory Policies Act (PURPA) years of the 1980s. Although in use prior to then, cogeneration plants proliferated as a result of the PURPA of 1978.
Cogeneration plants are commonly found in district heating systems of cities, central heating systems of larger buildings (e.g. hospitals, hotels, prisons) and are commonly used in the industry in thermal production processes for process water, cooling, steam production or CO 2 fertilization.
Cogeneration / Combined heat and Power (CHP) Cogeneration (cogen) through combined heat and power (CHP) is the simultaneous production of electricity with the recovery and utilisation heat. Cogeneration is a highly efficient form of energy conversion and it can achieve primary energy savings of approximately 40% by compared to the separate purchase of electricity from the national electricity grid and a gas boiler for onsite heating.
The cogeneration plant consists of one 5.2 MW Solar Turbine dual fuel turbine (natural gas and #2 low sulfur oil); one 6 MW Ideal generator; one Davis duct burner; one ERI heat recovery steam generator (HRSG) with a capacity of 25,000 PPH unfired and 40,000 PPH fired; and two Gardner Denver natural gas reciprocating compressors with lead/lag controls.
