Background technology
Boiler sootblowing steam is the steam that boiler is used for soot blowing, it is desirable to have certain degree of superheat and pressure.Wherein the degree of superheat is to steam
Difference between vapo(u)rous temperature of the stripping temperature under a certain pressure.In soot blowing process, the leading high speed injection of boiler sootblowing steam is steamed
Shock of steamy flow produces impulse force on fouling and slagging makes which come off.Thus the flow velocity of boiler sootblowing steam is higher, vapour density is bigger, soot blowing
Effect is better.Potential energy difference in high pressure that boiler sootblowing steam has and burner hearth between weak negative pressure defines the high speed of boiler sootblowing steam
Jetting flow power, wherein, in burner hearth, weak negative pressure is a constant definite value, thus the flow velocity of boiler sootblowing steam depends on boiler sootblowing steam institute
The pressure of the vapour source point of the high pressure having, i.e. boiler sootblowing steam.After boiler sootblowing steam enters burner hearth, pressure is drastically reduced, now
Steam can occur the reduction of self inflation temperature, and when the temperature is reduced to below saturation temperature, steam will condense into water droplet, volume

The acting ability of left and right, economy are very poor.Temperature-decreased pressure reducer pressure reduction is very big, and equipment is fragile.And Late reworking outlet pressure
It is too high, easily cause valve frequently to reveal, affect safety.
Cold steam again is the steam after steam turbine high-pressure cylinder steam discharge back boiler, and pressure is more than 1MPa, and vapor (steam) temperature is about 300
DEG C or so, and main boiler sootblowing steam fetches a little.Cold reentrancy steam typically only needs to 4MPa or so pressure, and which is through high pressure
Cylinder does work, and as boiler sootblowing steam very economical, but the degree of superheat is low, and part soot blowing effect is bad.Cold outlet vapor again is typically only needed
4MPa or so pressure is wanted, which does work through high pressure cylinder, as boiler sootblowing steam very economical, while outlet steam temperature degree of superheat liter
