boiler machine supplier
In hospitals steam has many uses ranging from heating water, central heating, laundry, hospital kitchen and sterilization. On average, less than 10% of hospital steam is used for sterilization. Steam is generated by a large central boiler machine supplier and then transferred to distribution points via a piping system.
Gas-fired steam boiler machine supplier is the main boiler of commercial water and residential water. However, from the point of view of boiler explosion and boiler corrosion in recent years, many steam hot water boiler workers are not very familiar with the maintenance and use of Fangkuai boiler or maturing boiler. Therefore, the water quality standard of steam hot water boiler is introduced firstly by the electromechanical technicians in this paper. 1. The installation requires the installation unit to have the technical strength before the installation, carries on the installation construction organization design, formulates the installation construction network plan. Supervisory engineers shall organize design, manufacturing and construction units to communicate and coordinate technology according to the specific conditions of the pumping station. Installation After the design audit of the construction organization is approved, the supervisory engineer will issue the start-up order, allowing the construction unit to enter the site for installation and construction. Set up construction units, establish a single project responsible person, clear the scope of responsibility, unified command. Installation personnel should study technical materials, familiar with drawings, master procedures, specifications and related technical procedures, master installation steps, methods and requirements, so that the installation quality meets the design requirements. 2. The installation plan is the main part of the construction work. The contents include: installation process, installation work plan and so on. The installation plan and construction schedule should be clearly defined in the installation plan. List Identify individual projects, sub-projects and their quantities throughout the project. The main, middle, first and second phases shall be separated, and then reasonably arranged for the construction period, personnel composition and various construction stages. The main task is to get the progress of each project to work together and connect with each other. The main requirements for gas-fired steam boilers are as follows: 1. When the rated evaporation of the boiler is greater than or equal to 6 t / h, the boiler shall be degassed. If the rated evaporation capacity is less than 6 t / h, if the local corrosion is found, the water supply should be deaerated and the oxygen content of the feed water of the steam turbine boiler should be adopted. Should be less than or equal to 0.05mg / L. 2. If it is difficult to determine the dissolved solid, it can be indirectly controlled by measuring conductivity or chloride ion (C1 -), but the relationship between dissolved solid and conductivity or the ratio of chloride to Cl- should be based on the test. Yes. The ratio relationship should be periodically re-tested and corrected. 3. The relative alkalinity of the fully welded structure boiler can be controlled. 4. Steam hot water boilers with rated evaporation of less than or equal to 2 t / h and steam hot water boilers and steam water boilers with rated steam pressure of 1.0MPa or less (such as no special requirements for steam and water quality) can also be treated in pots. However, it is necessary to monitor Steam hot water boiler scaling, corrosion and water quality, and make ingredients, sewage and cleaning work.
Hebei Cangzhou issued a "special program on the implementation of standards of governance boiler machine supplier." Emission standards for boiler treatment and corresponding indication made, as shown in details as follows.
First, the standard standard coal-fired boiler
1, before the end of September 2019, within the city of more than 35 tons of steam / hour ultra-low emission coal-fired boilers complete transformation, emissions of major pollutants to achieve ultra-low emission standards (dust ≤10mg / m³, SO2≤35mg / m³, NOx≤50mg / m³).
Before the end of the year 2/2020, the city eliminated 35 tons of steam / hour and coal-fired boiler, stove and stove operating a small coal stove, achieved within the city 35 steam tons / hour and the boiler "No Coal." Reserved 35 steam tons / hour and coal-fired boiler, stove and stove operating a small coal stove implementation of the special emission standards (dust ≤30mg / m3, SO2≤200mg / m3, NOx≤200mg / m3).
Retention of more than 35 tons of steam / h coal-fired boiler to install air pollution automatic monitoring facilities and networking with the environment department, to install a distributed control system (DCS system), real-time monitoring of pollutant emissions.
Second, gas-fired boiler
1, before the end of September 2019, the city completed two-thirds of the total number of units of low-nitrogen transformation gas boiler above. Among them, the central city of all gas-fired boiler and all the city's industrial and commercial gas-fired boilers to complete a full rebuilding mode low nitrogen.
2, the end of June 2020, the conventional gas boiler should be completed by transformation of a low nitrogen combustion, soot, sulfur dioxide and nitrogen oxide respectively 5mg / m³, 10mg / m³, 30mg / m³.
Third, the task
1, increase clean energy alternatives. In areas not covered by central heating pipe network, and vigorously promote geothermal, wind, solar and other clean energy, in an orderly way from coal to gas and coal to electricity, to change the power-based. In 2020, under the conditions of gas supply has been guaranteed, the city eliminated 35 tons of steam / hour and below the coal-fired boilers.
2, increase the coal management and control efforts. Coal infrared video monitoring devices to increase coal quality sampling efforts, to retain the blast furnace coal-fired boilers to be installed, Hebei coal to meet local standards "Industrial and domestic fuel coal" (DB13 / 208102014) non-coal power generation industry quality indicators .
3, strict new boiler access. Ⅲ class urban area and high-pollution fuel combustion zone ban municipal government designated a ban on new coal-fired boiler, a citywide ban on new 35 steam tons / hour and coal-fired boilers, the new 35 steam tons / hour of coal-fired boilers must in line with the municipal government of central heating planning or construction of industrial parks planning, energy efficiency reached AQSIQ "energy-saving technology supervision and management procedures boiler (TSGG0002-2010)" requirements, encourage the use of "energy efficient boiler promotion List" reached the level of energy efficiency standards boiler, pollutant emissions to meet emission standards require extremely low.
Predict water shortages hot water boiler machine supplier water scarcity is a common phenomenon that appears hot water boiler, usually have to pay a lot of attention. When the following phenomenon is the phenomenon of hot water boiler: a static water table does not fluctuate slightly, this phenomenon is false level, the fireman staff not recognizing, as a white water table glass 2 (tube), or pencil rod or slash-shaped plate placed behind the water table, looking through the water table, see as polylines, but continuously obtained when the stick or a slash, then the water in the water table has not, the alarm level 3 and other low-level alarm signal or an alarm device emits a low level signal is greater than the water steam flow 4, a sharp rise in temperature of the steam superheater 5, the boiler room smell burnt taste 6, 7 of the furnace top wall collapse, the drum 8, the furnace, tube furnace superheater heating surface modification, 9 Sheung heard economizer have abnormal impact or sudden leaks flue economizer four weeks, 10 take the white water vapor chimney smoke, found squib 11, inflation port detached. May only just a little hot water boiler water when the first three phenomena, would be a serious water shortage during the first three phenomena plus a phenomenon occurs. To remember.
