Problems solved by technology

From the perspective of operation, although the water-tube hot water boiler is superior to the water-fire tube shell hot water boiler in terms of safety performance, it has the problem of high steel consumption in boiler manufacturing; although the water-fire tube shell hot water boiler consumes less steel, there are The bottom of the boiler shell is prone to overheating, bulging and other damage accidents, especially when the operating load of the boiler is high or the water quality is poor, the accident frequency is higher, and the output of the boiler decreases significantly after the dust accumulates in the smoke tube; the tail of the tube frame hot water boiler It is a flag-type heating surface. During low-load operation, low-parameter operation or low-quality coal, the flag-type heating surface is prone to corrosion and clogging, which affects safe operation. During maintenance, only the entire flag-type heating surface can be replaced. Problems such as high maintenance costs

Embodiment Construction

[0011] The full-membrane corner tube-type hot water boiler of the present invention is realized in this way, which will be described in detail below in conjunction with the accompanying drawings. See figure 1 , figure 2 , the full-membrane corner tube hot water boiler of the present invention adopts a full-membrane wall structure, that is, a closed water-cooled structure is formed around the boiler, and the right wall-type water-cooled wall is arranged around the boiler. 1. The front wall-type water-cooled wall Water-cooled wall 2, left wall-type water-cooled wall 3 and rear wall-type water-cooled wall 6, furnace wall 8 and guard plate 9 are set outside, corner tubes 7 are set at the four corners of the boiler to support the boiler, and the boiler drum 10 is arranged horizontally on the boiler On the top of the front wall, the outlet header 12 is arranged on the upper part of the shaft I serpentine tube economizer 13 and the shaft II serpentine tube economizer 14, and the bo...

Abstract

The invention relates to a full-film type wall corner tube hot-water boiler, which is characterized in that a full-film type wall structure is adopted; the structure is a closed water cooling structure formed on the periphery of the boiler; a right wall film type water cooling wall, a front wall film type water cooling wall, a left wall film type water cooling wall and a rear wall film type watercooling wall are arranged on the periphery of the boiler; a chamber wall and a frame cover are arranged outside the boiler; corner tubes are arranged on four corners of the boiler to support the boiler; a boiler barrel is transversely arranged at the top of the front wall of the boiler; outlet headers are arranged at the upper part of a chimney I snake type coal economizer and a chimney II snake type coal economizer; and a fire grate and a deposit door are arranged at the bottom of the boiler. The invention is in the full-film type wall structure, so that a heating surface can freely expand to simplify the structure of the boiler and save steels. The light frame wall with full-film type wall has small heat storage; therefore, the boiler can be quickly cooled to avoid boiling away during unexpected power cut so as to ensure the boiler to be safer. The full-film type wall corner tube hot-water boiler has the characteristics of good sealing, investment conservation, good insulation performance, sufficient output, low temperature corrosion prevention, dust blockage prevention, convenient maintenance, low maintenance cost and the like.

Description

technical field [0001] The invention relates to a heating facility, in particular to a full-membrane corner tube hot water boiler. Background technique [0002] Compared with decentralized small-capacity boiler heating, urban central heating has the advantages of energy saving and reducing pollutant emissions. Therefore, in recent years, my country's central heating industry has developed rapidly, and it has also promoted the development and progress of large-capacity hot water boiler technology. In the prior art, large-capacity chain grate hot water boilers mainly include three series of single (double) drum water tube hot water boilers, water and fire tube shell hot water boilers and tube frame hot water boilers. There have also been various problems in varying degrees during operation, but they are still the main furnace type of central heating boilers in my country. With the continuous increase of boiler capacity and the continuous rise of steel prices, ensuring the saf...
