Do you know the scale does harm to the heating boiler?After a long period of operation, scale and corrosion will inevitably occur in heating boilers, which is one of the main causes of boiler accidents. My company as a professional boiler manufacturers, in order to arouse the attention of the vast number of users to boiler scale, The following professional staff of the boiler manufacturers introduce to you the harmfulness of boiler scale and waste a large amount of fuel because the thermal conductivity of the scale is only a fraction of that of steel, so the heat transfer will be blocked after scaling on the heated surface. In order to maintain a certain output of the boiler, it is necessary to raise the temperature on the side of the fire so as to cause the heat loss caused by outward radiation and exhaust smoke. Due to the different working pressure of the boiler, the scale class The quantity of fuel wasted is different with different thickness and thickness. According to the test and calculation, the loss of fuel increases with the increase of scale thickness. It is easy to make steel plate and pipe burned because of overheating. After boiler scaling, it is necessary to keep certain working pressure and evaporation, so the temperature of fire side can only be raised, but the thicker the scale, the lower the coefficient of thermal conductivity, the higher the temperature of fire side. Generally speaking, the temperature of boiler fire side is about 900 ℃, and the temperature of water side is about 190 ℃. When there is no scale, the temperature of the steel plate is about 230 ℃, and once the scale is about 1mm, the temperature of the steel plate is increased by 140 ℃ compared with that without scaling. Left and right. When the metal reaches a certain temperature, the plasticity index of the metal begins to decrease, and the metal will creep and deform because of the overheating when the temperature is higher. So boiler scaling is easy to burn the metal. The accidents caused by scale in boiler account for about 1/3 of the total boiler accidents due to increasing maintenance costs and decreasing service life. Boiler accidents not only cause damage to equipment but also threaten personal safety.

Electric hot water boiler has been powered by electricity as a heating sourceThe electric hot water boiler is also called the electric heating boiler, the electric bath boiler, etc. The electric hot water boiler is the production hot water that uses the latest electric heating technology and the control system design to complete the production hot water to satisfy the heating or the supply life, Fully automatic environmental protection boiler of hot water for bath. The electric boiler is a kind of mechanical equipment which uses dynamic electricity as the heating source, heats the heat medium water to a certain temperature parameter through the heat exchange part of the boiler and outputs the heat energy with rated working fluid to the outside. A hot water boiler is a boiler that produces hot water. It uses the heat released from fuel combustion or other heat energy (such as electric energy, solar energy, etc.) to heat water to a rated temperature. A thermal energy device. Then, electric hot water boiler is the hot water boiler that takes electric power as energy source and produces specified parameters and quality. The electric hot water boiler heats the water through the electric heating tube, realizes the heating and provides the life, washes the hot water with the bath, the boiler intelligence degree is high, the heating speed, the noise-free, the pollution-free, Is a combination of a number of cutting-edge technology and research and development of the latest generation of hot water boiler products. Electric hot water boiler can not only satisfy heating but also supply hot water separately. If heat exchanger is added to pipeline system, electric hot water boiler can meet both heating and bath requirements at the same time.

In order to promote technological progress and sustainable development, improve environmental quality and protect public health, recently, the Liaoning Provincial People's Government of air pollutants for coal-fired power plants developed specific criteria (hereinafter referred to as the "standard"). This is the first time a set of policies Liaoning Province for air pollutant coal power plant.

"Standard" provides for pollutant discharge limits, surveillance and monitoring requirements within the jurisdiction of coal-fired power plant in Liaoning Province atmospheric and fugitive emissions control requirements. Since the implementation of the standards, air pollutant emissions coal-fired power plants all within the jurisdiction of Liaoning Province will be executed in accordance with the provisions of this standard.

2, since January 1, 2019, the emission limits of existing single output and more than 300MW generating units supporting the provision of a coal-fired power generation boilers execution table.

3, since 1 December 2020, the emission limits of existing single output 300MW generating units supporting the coal-fired power generation boilers and other power boilers as specified in Table 1 execution.

Sampling the exhaust gas (1) power plant, to be carried out in a predetermined position in accordance with the type of monitor emissions monitoring contaminants. In the discharge of pollutants should be set up to monitor the position of long-term monitoring holes, sampling platform and related facilities. When the sampling platform height from the ground greater than 40m, should be set by a lift platforms, lifts or other convenient and safe facilities. No elevator or elevator building coal-fired power plants, when the sampling platform height from the ground greater than 20m, should be set up safe, convenient electric monitoring equipment hoisting facilities.

Composition structure (3) continuous monitoring system atmospheric pollutants, technical requirements, test items, test methods and installation, commissioning, acceptance, operation management, data processing, etc. according to the provisions of HJ75 and HJ76.

(5) continuous monitoring system meter of air pollutants detection sensitivity, detection limit, and should meet the range of low concentrations of pollutant emission monitoring technical requirements, the concentration of nitrogen oxides include nitric oxide (NO) and nitrogen dioxide (of NO2), Determination of nitric oxide only has the ability to configure the analytical device of nitrogen oxides NO2 / NO converter.

(7) for coal-fired power boiler emissions of air pollutants sampling monitoring, sampling frequency, the sampling time and the operating load requirements,, HJ / T397 and related predetermined low exhaust gas concentration monitoring is performed according to specifications GB / T16157.

(9) shall be in accordance with the provisions of the enterprise "Environmental Monitoring and Management Measures" and the HJ819, HJ820 requirements of pollutant emissions and its impact on environmental quality around to conduct their own surveillance, monitoring and save the original records, public information.

Determination of air pollutants fired power plant analysis are shown in Table 2. After the release of the present embodiment national standard method of monitoring criteria pollutants, such as applicability to meet the requirements, the same applies to the determination of the corresponding standard contaminants present.

2, responsible for overseeing the management of this standard by the executive authorities and the standardization of administrative departments above the county level environmental protection. The results of the environmental protection departments at all levels and other relevant units in the enterprise supervision and checks can be instantly sampled or monitored the scene as determining whether acts of sewage meet emissions standards based on the relevant environmental protection and the implementation of management measures.

25 tph SZS condensing gas-fired vertical steam boiler dealer in africa for non-ferrous industryAs the core equipment of the production project, the steam boiler provides heat energy for the production process such as thermal analysis and drying. Tianqi Lithium is the world's leading lithium-based new energy materials company, its business covers key stages of the lithium industry chain. The production base in Shehong, Sichuan is the starting point of Tianqi Lithium's business, with an annual production capacity of over 172,000 tons.Recently, Tianqi Lithium carried out comprehensive technological transformation for further expansion of production capacity.
