function of evaporator in steam boiler

10 tph SZW biomass-fired function of evaporator in steam boiler for pharmaceutical factoryThe state advocates energy-saving and emission-reduction policies and puts forward higher requirements for some equipment and production conditions. How to reduce energy consumption as much as possible on the premise of satisfying production requirements has become a headache for many pharmaceutical companies. Changbaishan Pharmaceutical Co., Ltd. is a modern high-tech pharmaceutical company that integrates scientific research, production, and marketing. The products are based on Chinese patent medicine. In fact, whether Western medicine or traditional Chinese medicine production requires a large amount of industrial steam to sterilize raw materials, device and equipment at high temperature. Changbaishan Pharmaceutical Company plans to add 10 tph biomass-fired steam boiler from ZOZEN boiler Co., Ltd. because of its business expansion needs. SZW series boilers are designed by ZOZEN according to the needs of the pharmaceutical industry for boilers. They takes advantage of the dregs generated during the combustion and reasonable allocation of the air, ensuring that the dregs burn out as a fuel, improving the fuel's combustion efficiency, and reducing the company's costs.

hot water boilers of ZOZEN have sufficient output, high thermal efficiency,

safety and reliability, which are suitable for civil heating. This can help the

Combustion gas, which has several function of evaporator in steam boiler 1, flameless combustion: the air which has been uniformly mixed with the fuel gas prior to combustion gas required, the excess air ratio is equal to a coefficient of excess air for complete combustion of the fuel, not required in the combustion process from the surrounding oxygen in the air to obtain, after the combustion gas and air mixture reaches the combustion zone can be completed in an instant. 2, the diffusion combustion: gas heating boiler fuel gas and air interdiffusion nozzle openings, and combustion. Shao Shao stability advantages, the structure of appliance is simple, but the flame is longer, easy to produce incomplete combustion and carbonization of the heated area. 3, premixed combustion: gas heating boiler burner usually used such combustion, a portion of the pre-combustion air is mixed in advance with the gas (primary air excess coefficient between 0.2-0.8), followed by combustion. The advantage is clear combustion flame, combustion strengthened, high thermal efficiency, but the unstable combustion, the primary control of high combustible component and air requirements.

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.

A boiler operates at the boiling point of the liquid. An evaporator operates at a temperature lower than this. Boiling can take place throughout a liquid, but evaporation only takes place at an open surface. An evaporator usually has some flow of gas past the surface to take away the vapor being produced.
