Boiler pressure method Sliding Parameters concepts and features 1, what pressure method sliding pressure starting means hospital fuel steam fire tube boiler before starting the turbine motor main steam valve closed, boiler ignition generate steam certain pressure and temperature, the steam turbine feed steam turn red . Turn red when the main steam pressure parameters generally 0.8 ~ 1.5MPa, live steam temperature of about 250 ℃. This method is currently widely used. 2, sliding pressure starting characteristics (1) the security is good. For a steam turbine, the turbine is entered since the low-temperature, low-pressure steam, the volume flow is large, and the steam temperature is increased gradually from low, so that uniform heating of the components of the steam turbine, the temperature rise quickly, to avoid excessive heat stress and differential expansion. The boiler, the low-temperature low-pressure steam flow increases through the superheater can be fully cooled, and promote water circulation, reducing the temperature difference between the wall of the drum. Each member uniformly expanded. (2) the economy is good. Steam generated by the boiler can be fully utilized, reducing the working medium and the heat loss, shorten the startup time, reduce fuel consumption. (3) of the steam temperature, steam pressure more stringent requirements on the machine, run the furnace operation requires close cooperation, complicated operation, low load operation and a long time, there is a downside to the combustion boiler and the water cycle.
Shunde main business of special sea oil production and processing, etc., in the course of special oil refining, a large amount of steam required for oil and gas extraction, distillation and extraction technology and other aspects, therefore, the hospital fuel steam fire tube boiler is supplied special sea oil processing technology company Shunde indispensable less equipment. As environmental policy progresses, the chemical industry as more polluting industries are highly valued the various departments of quality supervision, sea Shunde companies to follow the development of the State Environmental Protection pace, choose clean the boiler industry-leading fast Boiler cooperation with the parties by quickly assess the specific needs on-site estimates and sea Shunde, to provide a SZS series of 25 tons of steam water tube steam boiler (SZS25-2.0-YQ).

The necessity and significance of hospital fuel steam fire tube boiler cleaning: boiler after a long run, the inevitable emergence of scale, corrosion problems, these problems are due to the generation of scale, so that the heat transfer deterioration, resulting in reduced efficacy boiler. It is difficult to achieve nominal evaporation; and since the heat transfer is deteriorated, such that the metal overheating, under pressure boiler, furnace tube bulge occurs even explode; poor thermal conductivity, so that the fuel consumption is increased, increased operating costs, boiler shortened life expectancy. Therefore, the boiler scale, should take the necessary cleaning methods.
