general instruction of steam boilers

At the end of 2018, Yantai City, Shandong Provincial People's Government Office issued the "Yantai Blue Sky win the Battle of three-year action plan implementation details," "rules" that: in principle, to new natural gas cogeneration and gas chemical projects. Details are as follows.

Continued implementation of the total coal consumption control, by 2020, the city's total coal consumption control in less than 24.19 million tons. Developed and implemented 2018-- 2020 coal consumption reduction alternatives work, the coal consumption Yajian task decomposition implemented in urban counties. Strict control of new coal project approval, approval, filing, encourage natural gas, electricity and other clean energy alternative to coal consumption. Censorship perfect substitute for coal, improve coal reduction coefficient replace coal utilization efficiency low industry. All new, revision, and expansion projects are implemented coal coal reduction alternatives, strict implementation of alternative sources and alternative proportions.

The development of special programs, out of shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance, the following priority out of 300,000 kilowatts to run at least 20 years of pure condensing unit, run over 25 years and Condensate Pumping Units still can not reach ultra-low emission standards for coal-fired units. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units.

Accelerate the phase-out of coal-fired facilities tea furnace built in the urban counties of the region, operating a stove, grain storage and drying equipment. The city's ban on new 35 steam tons / hour and coal-fired boilers. 65 steam tons / hour or more coal-fired boilers on the basis of complete transformation of the ultra-low emissions, with the transformation of the conditions to complete all energy saving. Out of coal-fired boilers heating pipe network coverage range. In the area where no cogeneration district heating conditions, a plurality of existing coal-fired boilers, and the like in accordance with the principle of building a large-capacity volume replacement coal-fired boilers.

The implementation of non-fossil energy doubling action plan, by 2020, non-fossil fuels in energy consumption should reach its goal provincial requirements, the city's wind power, solar power, biomass power, pumped storage power generation, nuclear power and other new energy and renewable energy power generation capacity reach 7.05 million kilowatts. Where the conditions of availability of resources, to encourage the development of biomass cogeneration county, increase renewable energy consumptive, improve social proportion of the total electricity consumption of renewable energy generation.

System description: System boiler module can realize heating, hot water, heating and swimming pools can be used simultaneously. The system consists of a heating system, heat transfer systems, and thermal storage system, such as three delivery systems. Heating boiler system is the master module, according to actual needs to match the size of the total power. Thermal storage delivery system: plate heat exchanger by heat exchange through the heat delivered to the circulation pump storage tank, and then conveyed to heat a desired area through variable-speed pump. Heat exchange system through the heat exchanger is a plate exchanger for a gas boiler system and the terminal, application plate heat exchanger can effectively prevent contaminants from entering the circulatory system to the gas boiler can be reduced fouling, extend the life of the host. Gas condensation boiler module has the following benefits: multi-gas condensing boiler module modules work in conjunction with small size, high energy efficiency characteristics, can provide a plurality of different heat required for the heat source system.

Main steam temperature in the boiler when a hot start is less than the rated Why? Hot Start For the boiler itself, in fact, is to a certain stage of the whole process of Cold Start as a starting point. When the unit stopped running, the boiler cooling faster than the turbine. If the turbine is in a semi-hot or warm, cold boiler may already start operation of such boilers essentially as cold to warm, boosting, to try to meet the red hot state turbine revolutions required parameters for input large amount of fuel, but this time only by the amount of the bypass system and a steam exhaust air is not enough, so that the steam temperature rises rapidly, and the walls and high temperature. Also, because the combustion chamber and the flue outlet larger width, uneven temperature distribution in the furnace, the superheater tubes are not circle the steam flow rate, the temperature difference is large, causing local over-temperature superheater tubes. To prevent over-temperature superheater, extending its life, so to start the predetermined process in the main steam temperature should be lower than the rated 50 ~ 60 ℃.

in landfill or indiscriminately burnt creating environmental pollution, this is a huge amount of

energy being wasted away, which otherwise could have been effectively used as CFB steam boiler to generate electricity and reduce the demand on fossil fuel.

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (72,000 kPa or 1290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Steam Boiler | Working principle and Types of Boiler

Aug 22, 2018 · Fuel (generally coal) is bunt in a furnace and hot gasses are produced. These hot gasses come in contact with water vessel where the heat of these hot gases transfer to the water and consequently steam is produced in the boiler. Then this steam is piped to the turbine of thermal power plant.

Boiler controls help produce hot water or steam in a regulated, efficient, and safe manner. Combustion and operating controls regulate the rate of fuel use to meet the demand. The main operating control monitors hot water temperature or steam pressure and sends a signal to control the firing rate, the rate at which fuel and air enters the burner.
