Working principle and structural characteristics of steam boiler

Steam boiler has brought great convenience to industry. Steam boiler has driven the development of the times. The following is a brief introduction to the structural characteristics and working principle of steam boiler. Steam boiler is a machine that mainly produces steam, and many people use it, but many of them do not know much about its structure and working principle. It makes use of coal, oil, natural gas and other water-tube steam boilers with limited capacity and pressure. There is a large desire to space, and easy to arrange, steam boiler in a variety of forms. Water is heated in the drum into steam, and the heat emitted by fire in the furnace is the principle of a steam boiler. Work of steam boiler Principle:

1, the heat generated by pulverized coal combustion in the furnace is first absorbed by the water wall through radiative heat transfer, and the water boiling of the water wall is vaporized, producing a large amount of steam into the steam drum for steam separation (except for direct flow furnaces). The separated saturated steam enters the superheater and continues to absorb the flue gas heat at the top of the furnace and the horizontal flue and the tail flue through radiation and convection, and enables the superheated steam to reach the required working temperature. The steam boiler for power generation is usually equipped with a reheater, which is used to heat the steam after the high-pressure cylinder does work, and the reheat steam comes out of the reheater to go back to the middle, and the low-pressure cylinder continues to do the work to generate electricity.

2. When the pulverized coal stove is working, The position of the center of the flame will affect the amount of evaporation, generally speaking, if the center of the flame is low, the amount of evaporation will be large, and the position of the center of the flame will also affect the temperature of the superheated steam or reheated steam, as well as the high value of the flame center and the small amount of evaporation. When the flame center is low, the superheated steam, especially the reheated steam temperature, will be low and vice versa.

3, the arrangement of burners, as far as coal powder furnace is concerned, there are many kinds of combustion modes, such as front and rear wall, tangential combustion, double tangential combustion, and so on, each of which has its own characteristics. The influence on steam can not be directly determined because the same furnace can not apply the above-mentioned arrangement methods at the same time.

In general, there are many factors that affect the price of the boiler. ZG boiler 10 tons oil and gas water tube boiler is a very popular boiler in many industries such as food factories, paper mills, hotels, planting greenhouses. In many industries, the use of steam boilers is the equipment that is required for many processes. Heating boilers are also a demanding device. After statistics, the 10 ton boiler can adapt to many environments. The price of 10 tons of oil and gas boilers is a concern of many customers.

Such as hotel Home Hotel Group is one of the three major brands, in 300 cities in the country has nearly 2,000 hotels. Home Inns has won China Golden Pillow Award for Best Chinese economy hotel chain brand award, in 2014, Home Inns brand value of $ 420 million of selected China's top 100 brands. April 4, 2016, BTG hotel groups such as the privatization of the hotel purchase transaction has been completed delivery. In mid-2016, as a Beijing hotel with our preliminary communication, the urgent need two boilers work of heating and hot water supply. I related technical engineers and recommend it to calculate the number and size of the boiler on the hotel room as hotel Willy sharp V6-99 two models.

The sale of the burner type and range of applications markets burner has a range of many different types, different types of burners applied are not the same. The scope of application of the burner more extensive, can be applied to the engine and ignition stove, and it appears to people's lives has brought great convenience, it has been a lot of consumers like. Burner also known as integrated burner to oil and gas-based. Fuel is generally used in small and medium sized boilers, the fuel fan heater, baked (baked) and the small fuel tank furnace. Broadly speaking, civil stove, lighter, torch, engine burner means belong to the scope and special civil combustor burner. Flame atomizer a pre-mixed component structure, also known as combustion head. It is a mixed gas of the combustion flame jets and carriers like sample, more than a single slit type slot length of about 50mm and 100mm there are two kinds, slit width 0.5mm, the former for the nitrous oxide - acetylene flame, after by an air - acetylene flame. Generally made of stainless steel, but also of aluminum or brass. A single slit (single-slot) with three slits (three-slot) two kinds. Mike atomic fluorescence spectrometry using a burner (Mekerburner), which is shaped torch flame. Two kinds of sub-cooled and air-cooled. After washing with distilled water is often required to use, to prevent corrosion and plugging the gap.
