advantage and disadvantage of fire tube boiler and
When determining the advantage and disadvantage of fire tube boiler and capacity, the number of shower, bath size, hot water tank capacity, bather flow, average water consumption, etc. will affect the boiler capacity. For different bathing environments, such as shower and baths, the calculation of boiler capacity is different. There is a reference formula here. If each shower head uses 300kg of hot water per hour (water temperature is 40°C), each shower head has a boiler capacity of D(t/h)=300*(40-cold water temperature)/60. *10^4. This data is for reference only and will involve more data in the actual selection.
1, to confirm the nature of the scale prior to acid pickling, the thickness and range.
2, pickling work must be carried out under the experienced guidance of boiler technicians, and pickling solution after repeated demonstration, to develop practical and reliable pickling solution.
3, corrosion inhibitors which are inevitable regardless of the boiler will produce some corrosion; therefore, pickling should not be repeatedly used.
4, drum pressure element if cracks or other leakage defects, these defects must be clear prior to pickling, and then pickling work, or other undesirable leakage accident occurs.
5, pickling, the operator should wear protective equipment (gloves, anti-acid, anti-acid suits, masks anti-acid, anti-acid glasses, etc.), open doors and windows to enhance ventilation to avoid these acidic substances harmful to the body. Prohibited welding, smoking or open flames access operations in the workplace, to prevent hydrogen explosion caused personal injury and other economic losses.
6, before the boiler feed water pump should be pickled, the steam outlet and sewage pipes with a round blind board isolated emptying valve is opened, so that the smooth discharge of acid gases produced.
Over the last four decades CFB advantage and disadvantage of fire tube boiler and has come a long way from its humble beginnings as a robust small-scale industrial boiler technology routinely used to burn difficult fuels. Not only do boiler designs now extend to 800 MW, but CFB has gone ultra-supercritical (USC).
Fang faster work on clean fuel advantage and disadvantage of fire tube boiler ands more than twenty years, whether it is research and development or manufacturing fields have achieved remarkable results. The launch of the "Euromonitor 5" series boilers, the company's new low-nitrogen boiler, using advanced FGR combustion technology, nitrogen oxide emissions below 30mg / m3, our first-tier cities can be used normally. Remote monitoring system is to attract the attention of the participants. Jumping curve data, real-time display operating status boiler; detailed data analysis and fault early warning program, Fang fast "black technology", making the boiler to get rid of "silly Big Ben rough" image and become intelligent high-tech incarnation.
