In order to ensure the safe operation of the boiler and the safety of people's life and property, the design, manufacture, installation, use and maintenance of this series of boilers must strictly implement TSG G0001-2012 "Boiler Safety Technical Supervision Regulations" and JB/T10094 "General Technical Conditions for Industrial Boilers" ", GB1576-2008 "Industrial Boiler Water Quality", GB50273-2009 "Boiler Installation Engineering Construction and Acceptance Specifications", JB/T1612 "Boiler Hydraulic Test Technical Conditions" and other relevant national norms and standards. WNS series steam boilers are designed with a horizontal wet-back three-return fuel (gas) structure. The fuel burns in the furnace to generate high-temperature flue gas, which is discharged into the atmosphere through the return combustion chamber → first convection tube bundle → front smoke box → second convection tube bundle → rear smoke box → economizer (or condenser) → chimney. The corrugated furnace is used in the design of the furnace, which reduces the rigidity of the furnace and reduces the thermal deformation stress. Spring-loaded explosion-proof doors and inspection doors are installed in the return combustion chamber for easy maintenance and explosion-proofing. There are manholes on the furnace body of the horizontal boiler, which is convenient for the internal maintenance of the furnace shell. The smoke pipe adopts threaded smoke pipe, which makes the flue gas disturb in the smoke pipe, enhances the heat exchange effect and improves the thermal efficiency. The front and rear smoke boxes adopt a hinged light structure, which is convenient for opening and closing maintenance.
The mobile container boiler room is to fix all auxiliary equipment such as boiler, control system, soft water processor, soft water tank, feed pump, sub-cylinder, fuel tank and instrument valve, and realize the mobility of the overall equipment of the boiler room. It can run fully automatically when the power is turned on. The display instrument and control system of the boiler are all completed in the container. The container is equipped with lighting, doors, windows, drainage pipes and other facilities. With the characteristics of fast movement, it can be transported by car to various complex sites, such as oil fields, road construction sites, bridge construction sites, mobile units, field operations and other places that require boilers. The auxiliary equipment of the container boiler is complete, the installation is simple and fast, and the user only needs to assemble the water supply, steam supply pipeline and power supply at the place of use. Neat and beautiful appearance, durable.
In general understanding, a boiler is a piece of equipment that is installed and fixed in a boiler room with a traditional structure and cannot be moved. Such boilers cannot adapt to the heating needs of mobile units and field operations. In order to solve this demand, the boiler industry has added a new member-mobile container boiler room.
Containerized steam boiler equipment is widely used in various industries of modern industry to provide power and thermal energy for production and life. At the same time, with the development of production and society, urban heating is developing towards central heating;
The degree of automation of small boilers has also been continuously improved to meet the social requirements for environmental performance and performance of industrial boiler equipment. The manufacture of boiler products is mainly reflected in the development of various large-capacity boilers, fast-assembled boilers and fully automatic boilers. But at present, although there are quick-installed boilers, a boiler room needs to be built and professional installation is required. The construction period is still long and cannot be used immediately.
The purpose of the invention of the container steam boiler is to solve this problem. The container house type WNS series fuel (gas) steam boiler is a new product of the whole boiler. The boiler and its ancillary equipment are produced in the factory and assembled into a container room boiler, which is quickly assembled and delivered. The boiler site installation quantity is reduced, and its quality is guaranteed . Overcome the shortcomings and deficiencies of the prior art.
Containerized steam boiler is one such realization. There are containers and steam boilers. It is characterized in that the container is equipped with a fuel (gas) boiler, a computer control box, a water pump, a water tank, a fuel tank, a burner, a fully automatic water treatment equipment, a complete set of Valves, instruments and facilities in the boiler room, all equipment connection methods are conventional boiler connection and installation methods. The container is equipped with WNS series fuel (gas) boiler, 1m3 water tank and 1m3 fuel tank. The fuel tank can be replaced with a gas tank.
Among them, the boiler is mainly composed of a drum, front and rear smoke boxes, chassis, guard plates, and thermal insulation materials; the main heat exchange and heating surface in the boiler is composed of a corrugated furnace and a threaded smoke tube bundle. The board is No. 20 steel plate, the thermal insulation material is rock wool board with good performance, the boiler feed water is distributed and the boiler is equipped with a steam-water separation device.
The advantage is that the container is equipped with WNS series fuel (gas) boiler, computer control box, water pump, 1m3 water tank, 1m3 fuel tank, automatic water treatment equipment, a full set of valve instruments and other boiler room facilities.
The boiler can be transported as a whole when it leaves the factory and during use, and the design and installation process of the traditional boiler room is no longer required. It can be used after connecting with the external pipe network to realize the open-air operation of the boiler. And has the corresponding wind, rain, freezing and anti-corrosion functions.
The combustion equipment adopts an advanced automatic device control system, which is safe and reliable in operation , and is equipped with various safety protection devices. The threaded smoke pipe technology with high efficiency heat exchange is adopted in the furnace, which makes the overall structure of the boiler compact, small in size and light in weight.
This series of products has the characteristics of convenient movement, small footprint and low investment in infrastructure; it can burn a variety of fuels, is easy to maintain, saves energy, reduces consumption, and has a clean and beautiful appearance. It is an ideal environmentally friendly thermal equipment.
Boiler performance characteristics The boiler has a fully automatic operation function. Set the working pressure range according to the needs, and the boiler can be put into automatic operation. During operation, the boiler automatically adds water and stops the pump according to the change of water level; at the same time, with the change of load, the burner can adjust the first-stage and second-stage fire to ensure good load regulation.
With a variety of safety protection functions, the burner is automatically locked when the ignition is unsuccessful at one time . At this time, it is necessary to press the burner to repeat the operation button again. When the flame is suddenly turned off, the burner can also be automatically locked for protection, and it also has the function of oil shortage protection.
The container steam boiler consists of the following equipment: 1. The container is equipped with a fuel (gas) boiler 2, a computer control box 3, a water pump 4, a water tank 5, an oil tank 6, a burner 7, a fully automatic water treatment equipment 8, a full set of valves 9 All equipment connection methods of the instrument 10 and the facilities in the boiler room are conventional boiler connection and installation methods. The fuel tank can be replaced with a gas tank 11 . The whole container boiler room is equipped with all the facilities required for the operation of the boiler.

The water supply and oil supply pipelines can be directly introduced into the container and connected with the oil tank and water treatment equipment.
Working principle of the boiler On the flue gas side, the fuel is firstly atomized by the burner and then ignited and burned, and the required heat is input into the furnace, and the generated high-temperature flue gas conducts the first heat exchange with the radiation heating surface of the furnace; The second heat exchange is performed in the tube bundle area, and finally the flue gas is turned again into another part of the tube bundle area to complete the last heat exchange. This heat exchange is commonly known as the three-pass flue gas. The low-temperature flue gas after heat exchange is discharged into the atmosphere through the chimney.
