Wood Boiler Domestic Hot Water Overview
Wood boiler domestic hot water belongs to the SZL series boiler, it is a horizontal dual cylinder arranged, chain grating, designed by our technical personnel according to advanced technology and experiences from home and abroad. The technology, performance, and environmental protective index of this series of products reach the international advanced level, and this product is the mainstay in the boiler industry. This series of boilers absorbs the merits of the quick-fitting boiler, features with compact structure, the boiler's shop is story arranged, convenient for site installation, short in the construction period, cheap in cost, simple in operation, and etc. This series of wood pellet steam boiler is suitable for industrial and living steam consumption, the correspondent capacity hot water boiler is applied for industrial and civil heating purposes.
Wood boiler domestic hot water are mainly used for heating and bathing. The hot water boiler circulates the hot water in the heat preservation water tank through the hot water circulation pump, and heats the hot water in the water tank repeatedly to achieve the purpose of bathing; the hot water boiler circulates the hot water in the heating pipe through the hot water circulation pump, and passes through the radiator. Wood boiler domestic hot water can meet people's heating requirements; hot water boilers and hot water circulation pumps combined with heat exchangers can realize the dual functions of bathing and heating.

The industrial hot water boiler system uses water as the heating medium. It is widely used in residential and public buildings and industrial enterprise workshops. According to the heat medium parameters, it can be divided into low-temperature hot water (water supply temperature is lower than 100 ℃) and high-temperature hot water; according to the system circulation power, it can be divided into natural circulation and mechanical circulation; according to the source of hot water, it can be divided into direct supply mode and intermittent supply mode. Most of them choose the mode of supply.
The industrial hot water boiler system generally consists of hot water boilers, radiators, water supply pipes, return water pipes and expansion tanks, etc., and is widely used in civil and public buildings as well as factories of industrial and mining enterprises.

Cabinets Type of Wood Pellet Steam Boiler Control System
Types of control cabinets for wood pellet steam boiler: wall-mounted control cabinet, podium control cabinet, MCC vertical control cabinet, piano-style control cabinet, positive pressure explosion-proof control cabinets, and three-proof control cabinet. Each control cabinet we leave the factory has a unique number, and it has the function of mobile phone viewing. You can see the operating status of the boiler in real-time, such as temperature, water level, pressure, alarm record, etc. But the actual operation still needs to be completed by the staff in the boiler room. The control cabinets picture is shown as follows:
Wood Pellet Steam Boiler Features
| Wood Pellet Steam Boiler Features | Function |
| Manhole, inspection door |
· Manholes are set on the upper and the lower drum. Manhole opens conveniently and is good for overhauling and cleaning;
· Inspection door is set in the furnace for convenient overhauling and maintenance.
|
| Independent air bin |
· Set different quantities of independent air bin from front to rear grate according to different steam capacity; · Distribute air reasonably according to various fuel and combustion conditions to make sure that the fuel is totally fired. |
| Panel |
· Cold rolling pressed film forms concave-convex panel which has great rigidity, strength, and beauty. · Fixed by self-tapping screw and there is no welding spot. · After the rust is removed, the surface will be printed with corrosion prevention, finishing coat, and primer. |
| Chain grate | · Chain grate layer burning, scientific furnace, reasonable air distribution, full combustion of pellets fuel. |
| Spring full lift safety valve |
· The safety valve discharge capacity is calculated strictly; · When the system pressure exceeds the rated value, the safety valve will open decompression automatically to make sure that no accident would occur because of high system pressure. |
| Secondary air inlet |
· Disturb the furnace flue gas to ensure the total combustion of volatile matters. · Air volume makes up 30% of total air volume. The airspeed is around 50m/s · Air volume and air pressure of separate secondary fan is easy to be controlled and adjusted. |
