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...
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 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 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...
Natural gas boiler heating is an important livelihood project, and the design of natural gas boiler heating is related to whether the heating is safe, stable, efficient and environmentally friendly. As a professional supplier of natural gas boilers, ZOZEN Boiler has summarized a heating design solution for natural gas boilers.
The working principle of natural gas boiler heating is that the circulating water is transported to the boiler inlet by the circulating water pump, and after bein...
Industry boiler is an important thermal power device, which is widely used in factory power, building heating, people's life and other aspects, with a large demand and a wide variety. According to the different flue gas passes, gas-fired boilers are divided into two-pass and three-pass boiler structures. Here, ZOZEN Boiler focuses on the structure and process principle of the common three-pass boiler.
The first pass: after the fuel is atomized by the burner, the formed torch is filled i...
