As the "Star Pavilion" on the show, the arrival of fast boiler is attracted quite a stir. Guests and friends from all over the world friends are gathered in front of "fast Boiler" booth, feeling the charm to bring clean boiler. This is the third appearance in the fast side of the trade show, our booth set up in the middle of the field, in the light against the background, beautiful booth set off for the scene of different merchants brought extraordinary appeal.
ZG power plant biomass fired boiler is a new type field assemble chain grate boiler, with capacity is 20,35,45,65,75ton, high pressure: 3.82Mpa,5.29Mpa
The causes of boiler scale boiler water as a medium for heat exchange apparatus A specialty. During operation the surface of furnace and boiler water contact form thick layer of scale, over the years, people have dirt kinds of boiler scale due to the scale have been fully studied, introduced a variety of anti-scaling technology, but still not been completely resolved, while the development of antifouling cleaning technology, as an adjunct to maintain heating surface and the heat transfer surface. So, boiler scale is how did this happen? There are three main reasons: First, the boiler feed water impurities into the boiler, through continuous evaporation and condensation, boiler feed water, concentration of salts continuously increases, the degree of saturation or supersaturation, will be in the boiler metallic surface the precipitated precipitate. Second, with the increase of the boiler water temperature, the solubility of certain salts and inversely proportional to temperature, these salts at elevated temperatures, the solubility is drastically lowered opening formed scale. Third, the interaction of different salts or thermal decomposition to produce a compound difficult to dissolve. Boiler feed water in a continuous process of continuous evaporation, the pure water into steam by the boiler feeding the salt water continuous furnace substance was concentrated, the content of rising. When the boiler feedwater salinity level of saturation or over-saturation, salt materials will precipitate from the water, form a solid precipitate. Adhering a larger portion of their thermal load heating surface to form a hard or soft scale, another portion of the furnace was suspended in water with the boiler water circulating flows. When the heat receiving face of the poor circulation, the flow rate is low, then the deposition of scale on the heating surface to form a secondary, or deposited on the drum should not have high flow rates, a lower collection tank, dirt is formed, with the periodic sewage discharge from the furnace. Thus, generation of scale, in addition to the ingredients and contents of impurities in the boiler water related, but also to a large extent depends on the operating state of the boiler. The larger the water evaporation intensity, the higher circulation rate, the easier it is to generate water circulation easily broken loose precipitate, evaporation of the boiler assembly can reduce the number of scale on a surface. In contrast, evaporation intensity, the lower the cycle rate, the more easy to form scale on the surface of the evaporation boiler.
Boiler "Run" Tips: in all the major parameters of the boiler, main steam pressure to maintain stability is the key which only the steam pressure is stable, the remaining parameters to stabilize. Unstable steam pressure, steam temperature, the water level will also change, so first of all start from the pressure adjustment. Vapor pressure is divided into an outer and an inner interference disturbance, our plant, i.e. outside the external disturbance load generally little change, so change in vapor pressure are changed within the furnace i.e. interference caused by operating conditions, so holding furnace combustion conditions the stability is the stability of the vapor pressure. If the combustion conditions change, such as wind than powder, coal calorific value and other factors change, a pressure change occurs, requires us to be adjusted, thereby changing into a stable state of the combustion furnace transient state conditions.
