HTF susceptible to oxidation during heating, the acid value of the oil at a high temperature increases and the rate of change is large. Its kinematic viscosity gradually added, because HTF component thermal cracking at high temperatures, the thermal condensation reaction. Achievements pyrolysis reaction leads to the formation of small molecules, reducing its viscosity; and thermal condensation reaction to generate polymer products, its viscosity increases. A small amount of evaporation of small molecule compounds, total results so that the oil viscosity, carbon residue increases with increasing temperature. When the temperature is prone to use 300 ~ 400 ℃ thermal cracking to produce coke in pipes, equipment wall, leading to heat accumulation effect heat transfer efficiency pipeline, the pipeline oxide sludge poor mobility, speed up transfer oil aging failure, but also the furnace, Vertical gas pipeline section overheat oil furnace, impairing the mechanical strength of the threat to personal safety. HTF piping in scaling is not the same degree of narrowing of the pipeline road circulation area, increasing the friction, increased transportation energy consumption declined competence oil pipeline, and even sometimes lead to the initial setting of stopped-flow, etc. incidents occur. In addition, oil grease scorching can occur wall of resistance additions, adding energy production process, equipment life expectancy shortened dirt layer also makes the device smaller inner diameter Wuqiao Arts conducting oil furnace gas, oil flow pressure drop increases 300 000 kcal conducting oil furnace gas, the yield drop, the operating cycles of gas oil furnace, seriously affecting production. Oil furnace system, accumulation of grease, may be heterogeneous or multi-layered mixed fouling, cleaning method can only be cleared by step during a phase or layer, use multi-level needs cleaning process to ensure the removal of most of the fouling ability. Hot climate gas oil boiler repair: 1, on the Special Climate my conduct sunstroke, water, lightning, wind and other effective measures. 2, reducing gas oil boiler construction site temperature difference and humidity difference, suppress shortened. 3, strictly control the construction of gas oil boiler with the ratio to ensure the strength of the concrete itself, the selection of the construction to prevent the occurrence of cracks shorten quality and short life issues when temperatures at night a little at the end. 4, on the plastic cracked concrete because it happens in a plastic condition, if control of the main factors to carry out the land does not become harmful gas oil boiler repairs. In the construction of a gas oil boiler tissue hand panel care, timely detection and timely treatment can solve hand side. About shrinkage cracking, it should be used as a common problem of quality control of the main gas oil boiler repairs management. Wuqiao Arts conducting oil furnace gas, Arts boiler (certified), gas oil furnace provided by the Hebei Arts boiler limited liability company. Hebei Arts boiler limited liability company (www.yi-neng.cn) Hebei Cangzhou, industrial boilers and accessories leader over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . Boiler leadership in the arts with the staff warmly welcome all inquiries negotiations to create arts boiler better future.
