In 2020, the hotel's original heating equipment, a coal-fired hot water boiler, was in urgent need of purchasing a new boiler. DABONN provided it with a 2.1MW integrated condensing atmospheric pressure gas hot water boiler.
In 2020, the hotel's original heating equipment, a coal-fired hot water boiler, was in urgent need of purchasing a new boiler. Due to its long use, the accessories were greatly worn and the pollution was serious.
In the process of gradually getting to know DABONN, Le Meridien Hotel valued DABONN's excellent product performance and perfect post-service, and decided to cooperate with DABONN.
DABONN provided it with a 2.1MW integrated condensing atmospheric pressure gas hot water boiler.
The boiler provided by DABONN was fully equipped. After installation and debugging, everything was normal. We put it into use immediately without delaying the normal hotel heating.

This boiler is a product jointly developed and launched by DABONN and Tsinghua University. It passed the inspection by the National Inspection Center and was finally launched into the market.
The corrugated furnace bladder, threaded smoke pipes, new thermal insulation materials and focused treatment of vulnerable parts have improved the overall performance of the boiler, achieving high thermal efficiency and a longer service life.
In boiler equipment, the valve can play the role of opening and closing the pipeline, controlling the flow direction, and adjusting and controlling the parameters (temperature, pressure, and flow) of the conveying medium. The valve is a control component in the fluid conveying system, which has the functions of cut-off, regulation, diversion, prevention of backflow, voltage stabilization, diversion or overflow, and pressure relief. According to the specific function of the valve, it can be divided into a shut-off valve, check valve, regulating valve, and other models.

Atmospheric pressure hot water boilers are also called pressureless hot water boilers, which belong to the category of domestic boilers. It is a non-pressure hot water boiler with an air vent on the top and the boiler body is always operating at normal pressure. The main feature of the normal pressure hot water boiler is that the boiler is not pressure-bearing and has no safety hazards. It is mainly used for heating and producing hot water. It is one of our more common types of boilers.

The WDR electric pressure hot water boiler has a shell-type structure. A stainless steel heating tube is installed on the wall of the shell. Electric energy is converted into heat energy through the electric heating tube. The boiler has a compact structure, small size, flexible layout, and easy installation.

The lower part of the electric vacuum hot water boiler is a water chamber. A stainless steel heating tube is installed on the wall of the water chamber. Electric energy is converted into heat energy through the electric heating tube. The upper part is a steam space, in which a row of stainless steel tubes is inserted. Tubular heat exchanger. Since the entire boiler is under negative pressure, it is absolutely safe. The heat medium in the furnace does not enter, exit, increase or decrease during the entire operation of the boiler. It is only enclosed in the vacuum chamber of the boiler and transfers heat between the heat transfer tubes and heat exchangers of the boiler. The heat medium in the furnace is completely deoxygenated pure water, which has no corrosion or scale.

With the continuous emergence of high-rise buildings, the setting of chimneys in high-rise buildings has attracted more and more attention, which is also a very difficult problem. If it is not handled properly, it is likely to cause serious consequences of "disaster to the present and future generations". The steel chimney made of stainless steel, titanium steel composite plate, carbon steel, and other materials stands out because of its characteristics of heat preservation, effective durability, safety, and reliability.

The boiler is a double-drum longitudinal "D" type structure. The water, steam or steam-water mixture flows in the tubes. The flame burns and the flue gas flows outside the tubes, to ensure the good water circulation system, thus ensuring the long-term stable operation of the boiler.

The water tank is generally composed of a water inlet pipe, water outlet pipe (domestic water outlet pipe, fire water outlet pipe), overflow pipe, drainage pipe, and other pipes. To measure the quality of the water tank, it depends on how the welding technology is. Welding materials should comply with the current standards "Carbon Structural Steel" and "Carbon Steel Welding Rod"; butt welding is used for splicing steel plates, and other welding is fillet welds. Strengthen the coincidence.
