Phase out coal-fired 9783 d type boiler agent in kultis, promote air pollution control is an important measure to improve the air quality of the environment. Zhangjiakou City, Hebei Province, according to the central and provincial government deployment requirements, in-depth launched out of control for coal-fired boilers, and comprehensively promote the city's 35 tons of steam / coal-fired boiler sales and less "clear" work to ensure the city's air quality improved and enhanced.
The phase-out of coal-fired boiler from the following three points.
First, the coal-fired boilers carry out a comprehensive investigation work.
Depth investigation and the remodeling phase out coal-fired boilers and "coal to electricity", "coal to gas" and so on, electricity consumption by verifying the number of boilers and eliminated the need for the transformation of gas to develop a control list in 2018 coal-fired boilers to natural gas, electricity security for the ability to determine the "coal to electricity", the number of "coal to gas," the boiler. Do a boiler in a table, as well as finishing the complete elimination of the transformation of the way, rectification, acceptance, responsibility for people's list, to lay the foundation for the next phase out coal-fired boilers governance.
Second, carry out the phase-out coal-fired boilers.
Carry out a comprehensive phase-out 35 tons of steam / hour and below the coal-fired boiler, stove, operating a small coal stove, the main urban built-up areas and the urban fringe, and built-up areas within the county Economic Development Zone range, a ban on new coal-fired boilers other regional ban on new 35 steam tons / hour and below the coal-fired boilers. For central heating central heating in the official website of the area covered, when not incorporated central heating, heating mode using a variety of propulsion power, natural gas, industrial waste heat utilization, and energy from the source to control pollution.
Third, strongly promote the boiler-depth treatment.
Focus on pollution control bulk coal, comprehensive transformation of the use of coal boilers and generators. Stoker addition, stoker furnace, over the remaining 65 tons of steam / h coal-fired boiler to complete the transformation process ultra-low emissions, the city above 35 t steam / hour is then mounted boiler line monitoring devices, and environmental protection authorities and networking, production facilities and quality facilities simultaneously, real-time monitoring.
3.Enhanced load regulation.Can be adjusted within the range of load requirements freely.
4.Reduces the environmental pollution Greatly.Sulfides and oxides of nitrogen emissions produced by coal combustion meet standards.
5.Time to maintain a constant temperature Shorter,the cooling is slower, the time lag fire to about 6 hours,make the boiler operate normal.
6.High efficiency circulating fluidized bed boiler technology, small amount of maintenance, improve labor productivity, reduce production cost.
How Principle gas steam 9783 d type boiler agent in kulti steam boiler temperature waste gas problem is simple automatic temperature control? Gas-fired steam boiler can not do simple automatic temperature control, the risk will occur. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. Steam generated by the boiler and the pressure of the steam temperature of the heated liquid in strict correspondence relationship numerically. Small temperature changes cause large changes in pressure. And the temperature and reaction control with hysteresis characteristics with inertia, tends to achieve the desired detected temperature hysteresis value, even if the measures taken, the actual temperature will continue to change in the direction toward the original, it is easy to cause overpressure; while the evaporation of the boiler, the actual amount of steam pressure and a great relationship, if the constant temperature control, can cause large fluctuations in boiler pressure; furthermore the risk of boiler overheating caused by overpressure danger is far larger. Thus the steam boiler is usually a control outlet pressure, without controlling the temperature. Maintenance of gas steam boiler? Dry maintenance: Shutdown of the gas steam boiler discharge water released, the internal completely remove the dirt, rinse, drying Weihuo, not contacting the metal with lime. By weight quicklime, to the boiler volume 4 kilograms per cubic meter, then all manholes, hand holes, pipe valve closed, such as powdered lime broken into, i.e. to be replaced should be re-run the boiler quicklime removed. Gas-fired steam boiler shutdown after the release came out of water, the interior completely remove the dirt, rinse and refill the water has been treated, so that the water vapor exhaust out of the furnace, and then close all valves. Cold wet climates not care, so as not to damage the boiler furnace water freezes. Also repair and maintenance of steam boilers DZL series should strengthen the training and management of the fireman and the boiler, safe, stable and efficient operation. Gas-fired steam boiler waste water can be discharged directly do? Gas steam boiler in the absence of waste water pollution case can be directly discharged.
In dairy companies, the use of industrial 9783 d type boiler agent in kultis is essential. For example, steam boilers are inevitably used in fermentation, disinfection, and drying in the production of liquid milk. In the dairy industry, the use of steam generally includes: heat treatment of dairy products, steam processing for dairy products, pasteurization of liquid milk, and ultra-heat treatment (UHT) milk.
