Analysis of structural characteristics of condensing pressureless indirect heating hot water boiler

Condensing pressureless indirect heating hot water boiler structure:

The lower part of the condensing pressureless indirect heating hot water boiler has the same structure as the ordinary boiler, consisting of a combustion chamber and a heat transfer tube; the upper part is equipped with a heat exchanger, and the upper part of the furnace body is provided with an expansion water tank, since the whole boiler is In the no-pressure state, it is absolutely safe. The tail flue is added with a condenser to improve the heat efficiency. The heat medium water in the furnace does not enter during the operation of the boiler, and only transfers heat with the heat exchanger. The heat exchanger is strictly According to the manufacturing standards of shell-and-tube heat exchangers, the shell and tube are tested separately for water pressure.

Condensing pressureless indirect heating hot water boiler unit without pressure operation, safe and reliable: the upper part of the boiler is provided with expansion water tank, water level automatic control, no pressure operation, safe and reliable, omitting the responsible approval procedures.

Condensation pressureless indirect heating hot water boiler longevity: furnace water is only used as heat carrier. During operation, the oxygen in the water is heated and precipitated out of the furnace. The long-term use in the furnace will not cause oxygen corrosion. One-time addition of heat medium water, limited A small amount of calcium and magnesium ions are also heated and softened, and the boiler water does not increase or decrease during operation. Therefore, no scaling occurs in the boiler, which prolongs the service life of the boiler, which is more than twice the life of the general boiler, and is up to 20 years.

Compact structure, easy installation, low engineering cost: Condensing pressureless indirect heating hot water boiler adopts modular design, high-performance heat exchange components, compact structure, easy to transport, installed in small space, multiple units can be used in parallel, The process system is also very simple, eliminating the design and construction of the heat exchange station, saving engineering costs.

Main features of condensing pressureless indirect heating hot water boiler:

1. The overall structure is reasonable and compact, and it belongs to the boiler island type, which is in line with the fast-loading factory conditions. This product is composed of three parts at the factory; boiler main engine, chimney and piping system, in which the main engine and chimney part have been manufactured in the factory, the pipeline valves and instruments supported by the main machine have been randomly installed, and the main unit will be transported to the site. It can be assembled with the chimney. The vehicle can be commissioned by connecting the air source, power supply and water pipeline at the site. The installation cycle is greatly shortened and the product quality is guaranteed.

2 Advanced design performance.

The boiler main body is of integral structure, and the burner is assembled on the front smoke box cover, and the main body is mainly arranged with the heating surface and the combustion chamber portion. The structure is reasonable and compact, the steel consumption is low, the furnace adopts the bias waveform furnace, the thermal insulation layer adopts the new lightweight thermal insulation material, the outer packaging adopts the color thin plate, and the outer shape is packaged into a rectangular parallelepiped to make the boiler performance, weight and structural size. The appearance and appearance have obvious advanced and beautiful appearance compared with the domestic same-capacity products.

The boiler water supply equipment is arranged on the boiler base on the right side of the boiler so as to be integrated with the main machine, without further foundation.

3. The water circulation is simple, the structure of the pressure-bearing parts is reasonable, and it can operate safely under the condition of ensuring water quality.

4. The auxiliary auxiliary machine for condensing non-pressure indirect heating hot water boiler is complete, and the comprehensive technical performance is advanced.
