The common methods for boiling the gas-fired boiler:
1. Sodium carbonate (Na2CO3) or trisodium phosphate (Na3PO412H2O) and other drugs are used, and the dosage is calculated as per cubic meter of boiler volume, with the former being 5 kg and the latter being 3 kg;
2. Close the front manhole, hand hole and main steam valve (main water outlet valve), open the manhole of the upper drum, inject the prepared solution into the drum at one time, then close the manhole and open the emptying valve...
The combustion equipment of gas-fired boiler is burner and furnace. Before ignition, the burner should purge the furnace first, and then enter the ignition process. Why should the gas-fired boiler be purged before ignition?
Causes of purging before ignition of gas-fired boiler
Exhaust the pulverized coal and combustible gas that may accumulate in the furnace, flue and air preheater (or clean the pulverized coal accumulated in the primary air duct) to prevent deflagration during ignitio...
Heat transfer oil is an organic heat medium. As a medium, it is a good new energy-saving technology to circulate in liquid phase in other equipment systems to transfer heat. It is an excellent heat transfer medium with high temperature and low pressure heat transfer performance, remarkable energy saving effect, high stability, good heat transfer and high thermal efficiency.
After a long time of use, high-temperature heat transfer oil circulates in the hot oil furnace to transfer heat en...
With the enhancement of environmental awareness, gas-fired boilers have been popularized all over the country because of their high combustion efficiency and environmental protection emissions, and have become mainstream products in the market after coal-fired boilers. When enterprises buy boiler equipment, the size of gas boiler is also an important parameter. Here, ZOZEN Boiler, a professional gas boiler manufacturer, has summarized the size and model parameters of two common gas boilers for e...
With the strengthening of the awareness of cultivated land protection, the state has issued a policy of prohibiting the production of clay solid bricks all over the country, and some enterprises that produce and process clay solid bricks have gradually transformed and started to produce new wall building materials-aerated concrete, whose production cost and quality are much better than those of clay solid bricks. Therefore, aerated concrete blocks have become the development direction of new bui...
Hospitals, schools and cities in the north all use heating gas boilers for central heating in winter. Because of the high floor and long distance, the water pressure of heating gas boiler should meet the lift requirement. As a professional supplier of heating gas boilers, ZOZEN Boiler will take you to learn what the water pressure of heating gas boilers is.
Water pressure of gas-fired boiler
In addition to normal pressure, the water pressure of heating gas boiler is mainly 0.7MPa, 1.0M...
Thermal power generation is an important way to generate electricity. Coal is an important strategic resource in thermal power generation, and it is also one of the raw materials. Its process is actually very simple, that is, by burning coal, the hot water heated after burning is turned into water vapor, which drives the generator and is finally converted into electric energy. Then, some users ask how much electricity a ton of steam from a medium-temperature and medium-pressure boiler can genera...
Here, we'll address four of the key mechanical benefits that serpentine coil heaters have to offer.
1. Coil Replacement
Coil replacement in serpentine industrial coil heaters is notably easier than that in helical coil heaters. With serpentine coil thermal oil heaters, you can replace one tube at a time instead of replacing the entire coil. This can save you thousands of dollars on the cost of purchasing a new helical coil in its entirety. Because the coil replacement can be taken care of quickly, you'll also save hundreds of thousands of dollars by avoiding excess facility downtime.
