Hot-blast stove is a thermal power machine, which is a thermal equipment that integrates combustion and heat transfer process of hot air flow for technological needs. Generally, there are two major types, namely intermittent regenerative hot-blast stove and continuous heat exchange hot-blast stove. There are many varieties and complete series of hot-blast stoves, which are divided into hand-fired and machine-fired by adding coal, and coal, oil and gas stoves by fuel types. So does the ho...
WNS series oil/ gas fired boilers' main features are as below:
1. Combustion chamber adopts corrugated furnace to reduce the thermal stress and improve the safety of boiler;
2. Boiler body adopts wet back structure which is safe and reliable;
3. Threaded smoke tube enhances the heat transfer and reduces the steel consumption of boiler body;
4. Boiler is fully automatic controlled with automatic running and interlock protection function and the operation is simple.
5. Spiral finned tubes eco...
WNS series gas/oil fired boiler body adopts single drum, vertical type and wet back type structure. The drum is fixed on the boiler body base by two ends fixation and movable supports to guarantee the overall longitudinal thermal expansion of boiler. Corrugated furnace constitutes boiler combustion chamber, smoke fire tube bundle is convection heating surface of boiler and the flue gas channels have two types: bi-backhaul and tri-backhaul.
Energy-saving equipment is equipped at the rear part of...
With the continuous innovation of industrial technology, the boiler industry has produced a kind of circulating fluidized bed boiler equipment with high efficiency and low pollution through innovative research and development. What are the uses of circulating fluidized bed boiler? Here, ZOZEN Boiler will introduce the specific operation principle and the application of circulating fluidized bed boiler.
Working principle and characteristics of circulating fluidized bed boiler
Circulatin...
Organic heat carrier takes natural gas, oil, biomass and coal as fuel, takes heat-conducting oil as medium, and uses hot oil circulation pump to force the medium to circulate in liquid phase. It transfers the heat energy to the heating equipment and then returns to the heating furnace for reheating. It can obtain high working temperature at low pressure, and can control the medium operation with high precision. In order to strictly control boiler safety, relevant departments have formulated stri...
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.

Industry boiler is an important thermal power device, but the production of boiler NOx is the main component of environmental pollution, which not only causes acid rain but also destroys the ozone layer, and it is the key point of monitoring the products after boiler combustion. Here, ZOZEN Boiler will analyze the source and control method of boiler NOx for everyone.
Principle of NOx generation in boiler
Ultimately, the nitrogen source of boiler NOx is nothing more than fuel or air, so...
Boiler is a kind of energy equipment commonly used in industrial production, which is widely used in many industries, such as food, chemical industry, paper making, rubber, hospital and so on. Reciprocating grate boiler is also a kind of boiler product that is widely used. Considering that many users are unfamiliar with it, here, ZOZEN Boiler will explain the principle of lower reciprocating grate boiler and common furnace types.
The principle of reciprocating grate boiler
The principl...
