Problems solved by technology

[0006] 1. Due to the structure of the boiler, sufficient steam-water separation equipment cannot be arranged in the upper annular header of this type of boiler. At the same time, this type of boiler requires a compact layout, and the secondary separation device cannot be arranged in a large and complicated manner, resulting in the steam-water separation of this type of boiler. The separation effect is not good, and the steam humidity is higher than that of other steam boilers with sufficient steam-water separation equipment;
[0007] 2. The hydrophobic device in the external steam-water separation device directly drains high-temperature water without effective use, which reduces the efficiency of the boiler

Embodiment

[0032] Embodiment: a kind of steam-water separation type fuel gas vertical cross-flow steam boiler, such as image 3 As shown, it includes a heating surface pipe, an upper annular header 2, a lower annular header, a secondary steam-water separation header 4 and a burner 5, and the heating surface pipe communicates with the upper annular header 2 and the lower annular header. A combustion chamber is formed between the heating surface tube, the upper annular header 2 and the lower annular header, the burner 5 is arranged above the combustion chamber, and the upper annular header 2 is connected to the secondary The steam-water separation header 4 communicates with each other. There is a steam channel inside the secondary steam-water separation header 4, and a stainless steel wire ball 1 is arranged on the steam channel. In the secondary steam-water separation, the traditional corrugated plate in the secondary steam-water separation header is replaced by stainless steel wire balls...

Abstract

The invention discloses a steam-water separation type vertical oil-gas fired once-through steam boiler, which comprises a heating surface tube, an upper annular header, a lower annular header, a secondary steam-water separation header and a burner, wherein the upper annular header is communicated with the secondary steam-water separation header by a steam connecting tube; and a steam channel is arranged in the secondary steam-water separation header and is provided with a stainless steel wire ball thereon. According to the steam-water separation type vertical oil-gas fired once-through steam boiler, pores are formed on the conventional primary steam-water separation clapboard to form a second porous plate, and meanwhile, sealing plates on the two sides are welded additionally, so that the conventional simple separation way is changed, steam flows into the second porous plate and the primary separation efficiency is improved; in the secondary separation of steam and water, the corrugated plate in the conventional secondary steam-water separation header is replaced with the stainless steel wire ball, so that the manufacturing difficulty is reduced; and furthermore, a steam-water separation water return device is arranged at the lower part of the secondary steam-water separation header, so that the high-temperature water separated from the secondary steam-water separation header reenters the boiler to meet the requirement for energy conservation.

Description

technical field [0001] The invention belongs to the field of boilers, and mainly relates to a vertical fuel-fired and gas-fired cross-flow steam boiler with an improved steam-water separation structure. Background technique [0002] Boiler is a kind of heating equipment. It uses coal, oil gas, biomass, etc. as fuel to produce steam, hot water or other heat media through the heat generated by combustion, so as to meet various needs in social production. Coal combustion The flue gas produced will seriously pollute the environment and endanger human health, and the combustion technology and flue gas treatment are relatively complicated; the calorific value of biomass fuel is too low, and the boiler layout occupies a large space; Use, the combustion products have very little pollution to the environment, and the calorific value is very high. Compared with other fuel type boilers, its volume is small. At the same time, it uses fully automatic combustion equipment, which makes it ...
