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...
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...
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...
The boiler manhole-lids are mounted from the inside of the boiler so that the boiler pressure will help to keep them tight. Hence the manholes have to be elliptical in shape to make it possible to take the lid out from the boiler.
The natural gas boiler heats water into hot water, which can be used for heating and bathing. It is an important accessory of natural gas hot water boiler, and it can cooperate with other equipment to ensure the long-term stable operation of the boiler. As the user is consulting which valves are in the steam-water pipeline of natural gas hot water boiler, here, ZOZEN Boiler will answer for you.
What valves are there in the steam-water pipeline of natural gas boiler?
Various valves comm...
The change of heating pressure of natural gas will affect the normal operation of the boiler, resulting in anoxic combustion, deflagration, peroxide combustion, tempering and other phenomena. Then, what factors are generally related to the gas supply pressure of natural gas boilers, and how much should it be?
Gas supply pressure of boiler
The natural gas supply pressure of the boiler is mainly related to the tonnage of the boiler, and its general principle is:
If it is a gas boiler wi...
The natural gas testing of the boiler is to measure various thermal performance parameters of the boiler in a stable working condition (that is, in a normal combustion state), so as to judge the energy efficiency of the boiler. Natural gas testing can determine the thermal efficiency of the boiler, determine the size of each heat loss of the boiler, analyze the causes of each heat loss and seek ways to reduce the heat loss, so as to improve the energy efficiency of the boiler. What is the testin...
