When using coal stoves for heating in the Nordic winter, a chimney must be installed. During the coal burning process, condensation water drips out. Since most of the condensation water from the chimney is acidic, the chimney will rust. When water from the chimney is sprinkled on clothing, brown rust will form. Knowing the reasons for generating chimney water, we can choose a suitable stain removal method to solve it. Water stains on the chimney contain rust, so you can use a rust stain remover. The rust removal process is relatively simple and consists entirely of a chemical reaction. As long as the stain remover is used correctly, the rust stains will immediately turn into complexes dissolved in water. After washing with clean water, the stain removal process is complete.
In additions, it should be noted that the dyes used in some garments are metallic complex dyes, which can be damaged by rust preventative products, resulting in discoloration. Most of these textiles are dark gray or gray-blue viscose fibers or some wool textiles.
What should I do if the industrial boiler burns at 55 degrees and there is a lot of condensation water?
Because it can cause chimney fires, it should be cleaned regularly to avoid safety hazards.
The combination of condensed water and combustion exhaust gases will produce creosote, which is not only responsible for chimney fires, but is also very corrosive to the internal lining of the chimney, which will reduce the lifespan of the chimney. Proper chimney insulation can keep combustion exhaust gases high until they are vented outsideur, which can improve the suction force of the chimney, keep the interior of the chimney high and dry, and avoid condensation of water vapor.
How to deal with stove smoke: 1. Check whether the flue is blocked and clear it in time. 2. Check whether the chimney mouth faces the wind; It is recommended to point it vertically upwards and to use the chimney cap correctly (30 cm higher); 3. Check whether there is a baffle at the mouth of the chimney, which should be cleaned in time. 4. Check if the vertical height of the chimney; meets the standard (>4 meters). If the chimney is too thin or not high enough, the chimney should be replaced in time. 5. Check whether other equipment that can reduce extraction is installed on the flue gas riser; kitchen hood. If so, delete it. Smoke from the top should rise more than a meter above the eaves.
Whenhe gas boiler is running, especially when the cold furnace is started, flue gas condensation water is often produced on the rear heating surface of the boiler and on the rear smoke box, which causes the boiler to mistakenly think the boiler is leaking.
There are two main reasons for the generation of condensation water from flue gases:
(1) The water vapor contained in the flue gases condenses into water when the temperature is below the dew point. ;
(2) The boiler has high thermal efficiency and low exhaust flue gas temperature. Under rated load conditions, the boiler exhaust gas temperature is slightly higher than the flue gas dew point temperature, and it can operate economically and safely. However, when the boiler operates at low load for a long time, the flue gases. The youtemperature is below the dew point temperature of the flue gas and there will be condensation water flowing from the rear heating surface of the boiler and discharged from the boiler through the rear smoke box.
The condensate water generated by the hot water boiler during operation should be discharged from the boiler in time, because if the condensate water accumulates too much, it will affect the normal operation of the boiler. boiler and will cause serious damage to the rear smoke box door cover and the rear smoke box flange. The connection is leaking. Specific measures include:
(1) Establish a condensed water outlet at the rear smoke box
To allow condensed water to be evacuated in time, the outlet pipe generally should not be equipped with a valve but should be installed Water seal to prevent smoke from escaping from this tube.
(2) Install a nozzle tothe smoke box outlet
After the boiler flue gases are discharged from the smoke box and enter the chimney, the water vapor contained in the flue gases is still continuously cooled due to heat dissipation from the chimney. The soil condenses on the chimney wall, forming small water droplets that flow down the chimney wall. Therefore, a pipe must be installed at the chimney outlet so that the condensed water can. be discharged into the ditch or any drainage system.
The phenomenon of excessive condensation water in the flue gases of gas boilers should attract attention. Although the generation of condensation water is inevitable, the generation of excessive condensation water will inevitably affect the safe operation of the boiler.
