Removal of metallic scale and corrosion products generally requires chemical cleaning. Acid or chelant cleaning procedures vary greatly depending on individual circumstances. Chemical cleaning can improve the boiler heat rate and reduce the number of tube failures. It typically improves the stability of boiler chemistry.
Ensure that the vent valve on the boiler is open and check there is no pressure in the boiler. Check that the steam stop valve is closed. Check that all the valves for fuel are open, and let the fuel circulate through the system until it comes to the temperature required by the manufacturer recommendation.
A hot water boiler should be thoroughly inspected at first, including the accessory pipeline. Close the drain valve and open the gauge cock to discharge the air in the boiler.
Boiler feedwater treatment system includes two parts: pre-desalination system and ion exchange desalination system.
The pre-desalination system includes ultrafiltration system, reverse osmosis system, dosing system, chemical cleaning system, compressed air system, etc.
The ion exchange desalination system includes ion exchange system, acid-base regeneration system, compressed air system, wastewater neutralization treatment system, etc.
The boiler feedwater treatment methods ar...
The advantages of boiler fueled by the methanol can be concluded as follows:
a. The emission from boiler fueled by the methanol is very environmentally friendly, without sulfur, particulate matter, heavy metals and polycyclic aromatic hydrocarbons.
b. The methanol fuel is quite cost-effective.
c. The operation of boiler fueled by the methanol is safety. Compared with compressed natural gas, liquefied petroleum gas, gasoline and diesel fuel, methanol has the char...
A 10 tph boiler does not mean that the dead weight of the boiler is 10 tons. The ton of the 10 tph boiler is the heat load unit of the boiler, which is used in engineering, indicating that the rated evaporation capacity of the boiler is 10 t/h.
The boiler water film dust remover uses dust-containing gas to impact the inner wall of the dust remover or other special components, and forms a water film in some way, so that the dust in the flue gas is captured by the water film, thus purifying the gas.
Because a certain amount of air is usually dissolved in water, with the increase of temperature, the solubility of air decreases, and the gas is gradually separates from the water in the process of water circulation, and gradually gathers together to form large bubbles and even gas columns. Gas is often produced due to the water supplement, so the boiler exhaust valve must be used to avoid damage to the system.
