About boiler, daily attention to ten o'clock analysis of its original meaning, it means the pot is heated in a water container on the fire place burning stove refers to fuel the boiler including the two most from the pot and stove included. Today, we say that the boiler is the use of fuel or other energy hot water heating can become mechanical equipment of hot water or steam. Generating hot water or steam boiler may provide heat directly to the required industrial production and the people's living, the steam power plant can also be converted into mechanical energy by the generator can convert the mechanical energy into electrical energy. Because the frequency of use of the boiler is high, so it's for routine repairs and maintenance is also very important, here are ten aspects regarding boiler need attention, we divided into two parts to illustrate: First, note the boiler: (1) boiler factory, should be accompanied by quality certification, safety instructions and other supporting information. (2) boiler installation, maintenance and renovation should be obtained qualifications in this area for the job, not blindly, to avoid problems. (3) boiler to be registered before the registration can be used, and to be performed by professional job. (4) the operator while operating the boiler, and eight systems should abide by the rules and six records. (5) boiler and its safety accessories to be tested on a regular basis, no test can not be used. Second, boiler routine maintenance: (1) Check the boiler pressure gauge, water gauge, safety valve, sewage plant, the steam supply valve and the valve and verify its compliance with the performance requirements. (2) Check the automatic control device system meets the requirements. (3) Check the boiler feedwater system meets the requirements. (4) on the blower, induced draft fan, damper, etc., to see if intact, is working. (5) boiler should be regularly checked once a problem is found to be in time, so as not to affect the normal operation.
Phase out coal-fired boilers, 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.
For large and medium-sized enterprises which do not have heat supply from the central thermal power plant, when the continuous and stable steam consumption is above 20t/h, there are generally conditions for the establishment of self-provided thermal power plants. This kind of enterprise can choose 20t/h medium pressure boiler type or 35t/h medium pressure and sub-high pressure boiler, 1.5MW or 3MW back pressure type steam turbine-generator set, and build self-provided thermal power plant, which is mainly heating and auxiliary to generate electricity, and can obtain great economic benefits. Compared with the dispersed small-scale industrial boiler, the fuel consumption of the cogeneration is equal to that of the small-scale boiler due to the higher thermal efficiency of the boiler. Under the same heating conditions, it can be obtained by using co-generation of heat and power. Extra power.
How steam boiler steam metering? Whether or not electrically heated laundry equipment 50kgh steam generator iron is a steam boiler? Steam boiler steam metering, the corresponding meter is used to achieve the purpose, in general, may be used to remember the amount of steam flow meter, which can display the cumulative flow and the instantaneous flow, either in a liquid crystal display display, and water meters and can be the same counter. If it is the same for the steam boiler of multi-user, then, were installed in the branch line flow meter, to achieve their goals. Electrically heated steam generator, from a professional point of view, which is a water supply system, the automatic control system, furnace, heating systems and security systems to these, working principle thereof, by an automatic control means to ensure that during operation the controller normally liquid be opened and closed, and further, to ensure the normal operation of the steam generator. Therefore, from the definition and configuration point of view, it is not a steam boiler, these devices are two different devices.
