1. Mode boiler
In the process, the steam oven to between combustion regime that is to ensure the element will burn fuel more completely and if they have additional black smoke into the air oven attracts. If no visible smoke up must restrict air supply, reducing the appeal. If the smoke is gray with the best combustion mode. Than you put it in the oven must be spread evenly on the record and in small amounts to maintain a smooth flow on record. The coal and ash rake must be quickly and then close the oven door for coal lai. We should also pay attention to the thickness of the layer of charcoal, firewood on the record about 300mm. Slag and ash rake out the door by door dust. The rake slag, dust is carried out periodically and manipulation to increase the attractiveness of the oven by opening the shield to smoke.
2. Steam Supply
The furnace until the pressure in the furnace near equivalent maximum working pressure of the steam began to prepare. Before the water level should be slightly higher than normal. When the steam supply to the fire regime to ensure stability.
When we open the steam from the steam valve for heating a small amount of steam lines and drain standing on steam lines at about 10 ÷ 15 minutes, this time to observe the phenomenon of expansion tube and pipe supports, if normal, the main steam valve to steam goes all the way down. The steam valve to open slowly and if you open all the way down, then rotate the wheel backwards halfway around the steam valve.
To avoid water vapor and the water level in the boiler must be gradual, not for the excessive water in the oven under normal hydraulic pipes.
3. Water Supply
During operation of the boiler to maintain the water level in the boiler furnace operation should not be long in the lowest or highest limit. Boilers ensure regular water supply due to the intermediate water bottle or hand pump (pump power) to undertake this
4. Mode dirty furnace exhaust
The discharge of dirty boiler periodically made to the valve 6; 7
Depending on water levels in each mode uses the oven but it has been determined in a number of dirty exhaust ca. Hard water as the pH level higher number of boiler exhaust as much. At least in one case, they must discharge dirty 2 times daily discharge from 2 to 3 in each discharge in 10 to 15 seconds. Before discharging we should raise the water level in the boiler water level averages about 25 to 50 mm according to the gauge glass. Hydraulic pipes should be washed at least two times in a ca. Oven safety valve should be checked 1 time in 1 ca.
5. Water Requirements for flue
Level water hardness TH does not exceed the total 0,5mgdl / liter: PH = 7 ¸ 10
How to operate steam boilers and stop working steam boiler
II. STOP BOILER
1. Stop the oven normal
The boiler stops normally be done in the following order:
+ First Close steam valve and exhaust valve out by Posting gas safety valve channel and decreasing the pressure of the oven down while raising the water level to the top of the tube furnace by adding water fisheries in the boiler.
+ The second is to stop coal and coal closures, closed down smoke shield
+ The third is waiting for the oven to cool slowly with the regular monitoring of the operation of the boiler.
Removing the water from the boiler to hygiene must be approved by the person in charge of boiler and emptied by the end of the vapor pressure and water temperature oven 70-80 C while we perform channel valve full up slowly.
2. Stop the oven incident
Stop furnace malfunction is done in the following order
The first thing we terminate the supply of fuel and air into the furnace. shield smoke almost completely closed.
Monday Quick Scratch coal burning out of the combustion chamber.
Tuesday After termination of the fire, we shut off the valve and the smoke shield.
Wednesday Close steam valve and begins to evaporate out of the safety valve on the channel.
Thursday full of water supply to the furnace
+ To furnace cooled slowly under the supervision of the operation of boilers and particularly strictly prohibited to use water to extinguish the fire in the boiler
