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 15-ton natural gas boiler refers to the heat energy conversion equipment that uses natural gas, liquefied gas, city gas and other gas fuels as fuel, burns the heat released in the boiler, heats the water in the boiler, and converts it into hot water or steam. It is worth noting that the heating of natural gas boiler is completed by a complete system. Here, ZOZEN Boiler will introduces the standard system configuration of 15-ton natural gas boiler.

Boiler load refers to the capacity of generating steam per unit time, which is related to the output of the boiler in actual operation. When the boiler load occurs, its efficiency will also change. There are many conditions of boiler load. Here, ZOZEN Boiler will introduce you to what full boiler load means.
What does full boiler load mean?
The full load of the boiler is the state that the boiler reaches the rated load, and it is the heat provided by the heat medium produced every hour...
Boiler drum is made up of membrane wall, tube bundle, drum, furnace wall, header and other parts, among which boiler drum is a very important pressure component with many functions. This page introduces what the boiler drum is.
What is the boiler drum?
What is a boiler drum, the boiler drum is a cylindrical pressure vessel. Boiler drum is an important pressure component in natural circulation boiler and multiple forced circulation boiler. It is used for steam-water separation and steam...
In this question, what is the tonnage of a 6 million kcal boiler? Tonnage and 10,000 kcal are the expressions of boiler heat supply or boiler capacity. However, the relationship between different representations is unclear to many users.
Boiler capacity unit
Before the announcement of the equivalent tonnage of 6 million kcal boiler, the common boiler heat supply units in China were summarized:
Kcal/hour (Kcal/h) is a metric unit, which means the heat that the boiler can provide per ...
Boiler safety accessories mainly refer to pressure gauge, water level gauge, safety valve, steam-water valve, sewage valve and other accessories. These accessories are very important for the safe operation of the boiler, especially the pressure gauge, water level gauge and safety valve, which are the basic accessories to ensure the safe operation of the boiler. Therefore, they are usually called the three safety accessories of industrial boilers. Knowing the three safety accessories of boiler is...
The quality of steam directly affects the production capacity and production cost of enterprises, and improving the quality of steam is an important foundation to maintain the safe and economic operation of thermal equipment. ZOZEN Boiler fully studies the steam composition of the boiler, from raw water treatment to daily operation and maintenance, reasonably controls the steam quality according to the standard steam quality of the steam boiler, and prolongs the service life of the boiler.
