Steam soot blower | Shock wave soot blower | Sonic soot blower | |
Operating principle | The jet impinging kinetic energy of high pressure steam is used to remove ash and coking | The combustible gas is mixed with air to produce shock wave blowing ash after ignition and explosion | Using the vibration and disturbance of sound wave energy to blow ash |
Sound pressure | 80~100db | 160~170db | 130~150db |
Blowing effect | Good, to clear ash, coking is effective, to ash dead Angle is invalid. | Very good.It has good effect on removing accumulated ash and coking.But easily damage the tube wall. | Very good .The removal of the original ash has a certain role in preventing the deposition of ash, but the first removal of ash, coking is ineffective.Need to clear ash and coking first. |
Structure | Very omplex, the mechanical structure part is very complex | Complex, the gas tank must be frequently replaced, the control part of the air, gas flow detection, high-energy ignition control, gas leakage control | Simple, single solenoid valve, acoustic sub - chip |
Reliability | Lowest, mechanical failure rate, drive motor is easy to burn, stable operation period is short | Low, igniter, mixed gas tank has high temperature ablation, corrosion, a long - term risk of intensity reduction vessel blasting. Ignition instability, shock wave strength is strong and weak is not easy to control | High,vulnerable parts, diaphragm, rotary valve, etc |
Energy consumption | High ,each blow must consume the 0.7% steam produced by the boiler | Low, pulse operation, low gas and gas consumption | Lowest, miscellaneous air consumption |
Safety performance | Low, boiler tube tube wall corrosion, product tube burst accident | Lowest , danger of explosion in boiler or return explosive | High, pure air as the medium for safe and clean |
Apply | Convection tube bundle heating surface | All the heating surfaces | All the heating surfaces |
