1.2, high-temperature smoke discharged from the lower smoke passing channel enters a front smoke box (a second return stroke); and the smoke enters the inlet of the upper smoke passing channel through the front smoke box and is discharged from the smoke outlet (smoke outlet of the evaporator) of the upper smoke passing channel (third return stroke). Thereby completing the whole smoke circulation process from the fuel combustion to the smoke discharge.
2. Water supply cycle and heating cycle of evaporator:
2.1 cold water (purified water) enters the arc-shaped water tank through a water inlet on the upper part of the arc-shaped water tank on one side of the flue gas condenser, and is heated by the flue gas condenser, heated hot water enters the arc-shaped water tank on the other side of the flue gas condenser, and then is discharged from a hot water outlet on the upper part of the arc-shaped water tank on the other side and enters the water supply header on two sides of the evaporator body. And enters the water inlet branch pipes at two sides of the body through the water supply header (each water inlet branch pipe is provided with a control valve); then enters each component collection box through a water inlet branch pipe, is heated by the evaporator body and then turns into water vapor which enters the upper steam pocket of the evaporator.
2.2, the steam-water mixture entering the upper steam drum is output to steam equipment through a steam outlet of the evaporator after being separated by a steam-water separation device arranged in the upper steam drum. Thereby completing the whole heating cycle from cold water entry to steam output.
3. Safety control:
3.1 Water supply control
The water level of the evaporator body is automatically controlled through water level meters and water level sensors arranged on two sides of the evaporator body; when the water level of the evaporator body drops, under the electrical interlocking action of the water level sensors at the two sides and the electric feed pump, the electric feed pump automatically starts to supplement water for the evaporator body system; ensure the normal water level of the evaporator body.
3.2 pressure control
3.2.1, monitoring the operating pressure of the evaporator through a pressure gauge.
3.2.2, when the evaporator normally runs, the pressure controller and the pressure relief safety valve are in a static state; when the operating pressure of the evaporator rises and exceeds the set pressure, the pressure controller instantly cuts off the power supplies of the external blower and the external induced draft fan through the electric interlocking device, so that the external blower and the external induced draft fan stop supplying air and inducing air, and the rapid combustion of fuel in the hearth is stopped; the temperature of the hearth is reduced. Meanwhile, the pressure relief safety valve can be opened instantly for pressure relief; ensuring the safety. After the pressure is reduced to a normal value (no abnormal factor), each functional configuration can run normally.
