Hot water boilers and with plc controller industrial steam boilers What are the differences:? Hot water boilers and steam boilers What is the difference between the boiler heat transfer fuel to the respective equipment important thermal device is now being widely used aspects of industrial production and heating, etc.?. Popular in the boiler is in the range of steam boilers and hot water boilers both types, always a lot of people only know the boiler heating equipment, but can not tell the specific boiler respectively. Today, fast boiler manufacturers gave you explain: hot water boilers and steam boilers What are the differences On the surface, we can understand the heating method of heating hot water boilers and steam boilers used is not the same, but the hot water? the gap between the boiler and the steam boiler not only that, specifically in what way are divided into the following points:? 1, different output media: this we can see literally out of hot water as the medium boiler output of hot water, medium boiler steam output of steam. First, the user can according to their demand for the output media, select the appropriate boiler. 2, except the space occupied by: a steam boiler pressure vessel, steam formed by heating water vapor compression achieved after heating, and less area of ​​the pressure vessel is used, the hot water boiler is an unpressurized vessel with the hot water temperature to achieve heating, professional hot water boiler normally occupied by a large place, but to achieve better security of non-use of safety pressure vessel to better ensure users. 3, heating at different rates: the use of a steam boiler in the generation of heat due to water evaporation is required to ensure a large heat of combustion to produce steam, and therefore the temperature rise speed faster speed fever; hot water boiler in use by heating the water to ensure that the temperature , better heat capacity of water, so it can better maintain heating heat. 4, different heating range: since the heat storage capacity of water and steam gaps is large, high-volume pump hot water boiler can be conveyed with transport distance less heat loss can achieve large-scale delivery of hot water requirements. Since the steam boiler and the steam quickly freezes, it may cause the transport distance when the water dip, the two kinds of the boiler plant can withstand heat supply different range.

Of course, this does not mean to do all these, with plc controller industrial steam boilers will be good, inspected once every two or three months, see if you need lime, etc., to ensure that the oven is dry, there is no other erosion.

To comprehensively promote the prevention of air pollution control work, steadily enhance the quality of atmospheric environment, located in the northern part of Heilongjiang Province held a mobilization meeting Sunwu out of small coal-fired boilers to May 7.

Conference announced the "2019 Sunwu urban area out of 10 tons of steam per hour and coal-fired boiler embodiment."

To promote the elimination of built-up area of ​​small coal-fired boiler work, the relevant departments should strictly follow the higher level requirements, the investigation to find out the use of coal-fired boilers and urban planning area of ​​built-up areas, with their own reality, do a good job to implement; should attach great importance to raise awareness, according to the embodiment and objectives, and take various measures to actively promote the complete phase-out of coal-fired boilers small task; to actively publicize the relevant policies, regulations and requirements to the boiler owners, guided by the responsibility to implement, clear time node . To seek truth from facts, objective science, policy guidance, strict enforcement of the principle, in order to reduce air pollution, improve air quality and protect people's health as the goal, according to the classification regulation, departmental interaction, Duocuobingju, the overall advancement of the process steps to form a government command , business differentiation, market-driven, effective supervision, public participation in new air pollution control mechanisms, to promote the phase-out of coal-fired boilers built-up urban area.

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.
