China recovery boiler agitator

Boiler not cleaned What are the dangers china recovery boiler agitator daily to do the cleaning work, the scale should be cleaned, so as to avoid unnecessary losses, which harm the following look at the boiler scale: 1, causing the metal heating surface of boiler overheating, damage to the boiler, shorten life. Boiler heating surface green scale, cooling the metal wall surface is affected, resulting in increased wall temperature, the mechanical strength of the metal material is reduced, resulting in heating surface deformation, bulge, burst pipes and the like, or even a serious explosion. Damage to the boiler, affecting life. 2, to reduce the evaporation boiler, reducing the thermal efficiency of the boiler, waste of fuel. The presence of boiler scale is equivalent to an additional layer of resistance heating surface, because the scale is lower than the thermal conductivity of steel is large, hindering heat transfer, the heat released by combustion of fuel can not be effectively transferred to the water, water vapor can not be measured heat , with the exhaust gas side of heat is lost, and therefore to reduce the boiler output, fuel waste. According to statistics, the junction of a millimeter scale, about 2 to 3% waste fuel. 3, disruption of normal boiler water circulation, forced shutdown maintenance, increase maintenance costs. After water boiler fouling, reduced flow cross-section of the inner tube, the flow of power to increase the water cycle, even when serious completely blocked. Disrupted and boiler water circulation pipe burn, forced shutdown for maintenance. Waste of human and material resources, resulting in losses. In short scale great harm to the boiler, the boiler can not be safe and economic operation. Explosion-proof doors too heavy or inadequate pressure relief area; Exhaust Gas Temperature unreasonable. Caused by poor management of the boiler running water or boiler filled with water; poor management of water quality caused by boiler scaling; oxygen poor metal heating surface corrosion; sewage is not timely boiler water alkalinity is too high; adjust the boiler is not timely adverse atomization, incomplete combustion, flame instability or skewed; the fault itself or combustion burner system failure caused by boiler flameout. In summary, boilers and process design supporting improper installation, operation mismanagement can cause accidents occurred boiler, enterprises and workers to bring the loss of life and property. As long as we understand and master the hidden laws of boiler accident, strict boiler design, boiler installation, boiler management, and constantly improve and perfect the boiler management method, you can while avoiding disadvantages, to avoid boiler accident.

Coal received from the mines is stored in the coal yard adjacent to the power plant. It is then conveyed on a daily basis to the china recovery boiler agitator and stored in a ‘Coal Silo’. ‘Coal feeders’ continuously feed the required amount of coal to the ‘Coal Pulverisers’.

For pollutant emissions are out or do not meet the requirements dealt with by the environmental protection department according to the law, the quality supervision department cooperate with law scrapped boiler, write-offs.

Third, the time node

"Notice" announced the schedule for the remediation activities: biomass briquette boiler before June carding meet the special requirements of the boiler, the development of monitoring plans by the local environmental protection department, by supervisory monitoring, enterprise self-monitoring measures to ensure that in 2018 exhaust gas monitoring complete biomass fired boiler is in the list before the end of the boiler to investigate and punish excessive emissions.

7 to 10 months focusing on remediation biomass briquette boilers do not meet the special requirements of the boiler. Since August, the quality supervision departments throughout the province last month to the cancellation of the 5th of each month, scrap, corrective actions and a list of biomass briquette boiler re-enable the exchange to the same level of environmental protection department, the environmental protection department of the list with boiler organizations atmospheric monitoring pollutants.

In addition, quality inspection departments to be before the end of 2018, before the end of 62,019 years to complete before the end of October 2019 were 30%, 70%, to urge the rectification work 100% of the boiler problem.

After you have a list of remediation raw material briquette boilers, by supervisory monitoring, self-monitoring and other measures to organize corporate environmental protection departments in the country to receive quality supervision departments to provide complete exhaust gas monitoring within two months, to ensure that all students complete before the end of 2019 material fired boiler emissions monitoring.

Fourth, the work requirements
