Vertical Type Coal Fired Steam Boiler
To implement the "Blue Sky Hohhot to win the Battle of three-year action plan," Hohhot ecological Environment Agency and vigorously promote the city's coal-fired boilers mentioned standard transformation and treatment, formulated the "65 steam tons / hour or more coal-fired boiler and governance to promote the program." clearly this year will focus on the 65 steam tons / hour or more coal-fired boilers and in particular the implementation of ultra low emission limit values renovation work to further reduce emissions from coal-fired boiler pollution, improve the city's quality of atmospheric environment.
Program clearly states that the city has 58 coal-fired boilers will be completed before the end of the transformation, in which five large-scale district heating enterprises 65 steam tons / hour and over the implementation of ultra-low emission coal-fired boilers transformation,
16 65 steam tons / hour or more coal-fired hot water boiler to complete the transformation of governance. To ensure the smooth implementation of the mentioned standard treatment project, municipal environment bureau called on all localities in strict accordance with the "grid" management approach, down to every level will be the task of transformation, to the people, the letter coal-fired boiler to complete the task, each Related enterprises should play the main role, strict compliance with environmental laws and regulations and energy-saving standards, to complete the task on time.
To step up supervision and municipal environment bureau set up a special steering committee to implement the "Fortnight scheduling system", the city's coal-fired boilers governance supervision, the work of the task is not implemented, governance behind schedule, promote ineffective areas and enterprises to implement early warning and interviews, due to the unfinished task of accountability.
Gas boiler refers to a container for generating steam and hot water from natural gas(Calorific value 10000 kcal/Nm³), LPG(Calorific value 22929 kcal/Nm³), artificial gas(such as city coal gas, Calorific value 3000-4000 kcal/Nm³), biogas(Calorific value 5200-6000 kcal/Nm³) and other fuels. In general, gas boilers are usually packaged boilers.
How to improve the energy efficiency of industrial boilers 1, focusing on the transformation of practicality (1) above to recover waste heat can be effectively used. For example: high temperature organic heat boiler flue gas, but the process does not require the production of steam and hot water, attention should be considered heated by flue gas waste heat recovery techniques combustion air. (2) improved gas boiler should focus on energy-saving technologies improve the automation level of combustion control, precise control of the combustion state. (3) Consider first the application of energy-saving technologies and sophisticated equipment. 2, considering the technical nature to further improve the thermal efficiency of industrial boilers, it is necessary to consider new energy-saving technologies and equipment. Advanced (1) energy conservation technology and equipment, difficult to implement. Such as: waste heat recovery heat exchanger and the new technology: heat pipe technology, the condensed waste heat recovery technology; new water treatment device: microbial fouling and electromagnetic processing techniques (e.g., hydraulics); combustion automatic control technology. (2) spraying pulverized coal combustion technology (stratified combustion mode and suspension-fired boilers) design, construction and operation of high demand management, oxyfuel technology, such as high temperature air combustion technologies require large investments. 3, forming a complete transformation handle (1) must be considered boiler energy saving, heat insulation of synchronization is complete, sealing, and improved methods of burning fuel adjustment, and the fuel air distribution system of the inverter, reduced nicotinamide tube improved resistance to treatment. (2) pay attention to clean the boiler heating surface, and providing technical improvements boiler water, slag, ash, etc., to ensure that the boiler has good heat transfer properties. (3) the necessary training for technical operations and daily management of energy-saving equipment.
