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...
Boiler is a kind of important heating equipment in the process of industrial production, which is related to the economic development of enterprises. Users often meet the names of 1.2 million kcal boilers and 35 million kcal boilers when selecting the type. What does boiler kcal mean?
Kcal is the unit to describe heat. As the name implies, boiler kcal refers to the heating capacity of boiler. The conversion between boiler kcal is 1 kcal =1 kcal = 4,184 joules.

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...
An Interlock in the boiler’s control system is a programmed or hardwired condition that forces a device to be in a pre-determined or permissive state before the process can continue.
Depending on design pressure, fuel type, either liquid, gas or solid, all steam boiler require interlocks to sequence the operation and to prevent damage to the boiler. Examples of such devices are High or Low Boiler Drum Water Level, Low Boiler Feed Pump Pressure, High or Low Fuel pressure, High or Low Atomization pressure (oil fired), Proof of Ignition, Proof of Flame, FD and/or ID (solid fuel) Fan Motor Operation or combustion air pressure, Damper or Valve position and High Boiler Steam Pressure as well as O2 and furnace temperature.
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...
