school gas hot water fire tube boiler

Gas hot water school hot water fire tube boiler gas hot water boiler water quality standards and parameters of different capacities, in accordance with various operating conditions, the level of water treatment technologies and different long run, have different quality standard requirements. For details, see table below: This table is our current national standard "industrial boiler water quality" performance standards (GB1576-2008) mentioned. 1, the outlet for the rated steam pressure <2.5MPa, water as a medium, and a fixed soft drinks dual boiler hot water boiler, general use outside the boiler water treatment chemical, boiler water and feed water quality should meet the requirements of the table. 2, the rated evaporation <2t / h, and the rated steam pressure <1.0MPa gas hot water boiler of the boiler may also be employed and soft drinks dual dosing process in the boiler, the boiler must structure, corrosion and quality strengthen oversight, good dosing, sewage and cleaning, water quality should meet the requirements of the table. 3, pressure hot water boiler feed water for boiler water treatment should be carried out. 4, for hot water boilers and pressure hot water boiler rated power ≤4.2MW, you can also do the dosing process inside the boiler. 5, Feedwater should be outside the boiler water treatment chemical. 6, waste heat boiler water quality indicators and electric water boiler should be consistent with the type of required parameters with the boiler

Gas school hot water fire tube boiler shutdown normal shutdown process step is one step in the process of boiler operation is essential to understand the shutdown processing methods to ensure more long-term operating life of boiler. When the boiler the following faults can temporarily shutdown for maintenance. Expansion port, leakage rivet joints; tube, the waterwall tubes, damage to the heating surface tube leakage; drum in contact with the flue gas, set top box, a heat insulating material off the downcomer; water supply system, a combustion system, the occurrence of breakage safety accessories . Shutdown of the gas boiler normal (full shutdown, maintenance shutdown) Step 1, in order to stop the burner, for closing the valve. At the same time feed water to the boiler, 2cm above the normal water level reaches the stop water supply, reduce the pressure. 2, close the main steam valve, open the traps, steam boiler, water cut off. 3, the electric boiler feed water control valve closed and the manual valve, boiler feed water cut. 4, steam pressure may be lowered to the water supply and drainage operations alternately 0, the pot water temperature is gradually lowered. When the temperature dropped to 50 ℃ (not hot when hand potshell head with or touch), the entire pot of water may be drained. Should be preceded by opening the drain valve or air valve above the boiler, this time into the furnace maintenance, shutdown must be kept slow cooling, rapid cooling is prohibited. From the shutdown to be able to enter the furnace maintenance, cooling time is not less than 24 hours. 5, sales of more than 24 shutdown, to total gas supply valve is closed, opens the gas pipe to completely drain the subjective dispensing gas.

Foshan Gaoming Liu Ling Textile Dyeing and Finishing Co., Ltd. was founded in 2007, enterprises comprehensive strength, advanced processing equipment, detection means perfect, has a complete quality assurance system, the introduction into a large number of advanced production equipment, to ensure that technical standards and products stable to improve the quality of laid a solid foundation, enjoy a high reputation in the industry. Liu Ling Gao textile company twice with my company were to buy a 20 tons of steam and a whole 10 tons of steam condensing steam school hot water fire tube boiler fuel gas for the production of textile dyeing and finishing company. Fang fast with strong comprehensive strength and improve the service system to win the favor of the other side, communication from the initial to the final boiler factory-installed square fast all uphold the customer's perspective to think and observe the service concept, for the sake of clever Liu Ling textile companies according to the company's actual demand for textiles, the development of specific programs.

Effect of energy consumption because of the vertical stack of hot water school hot water fire tube boiler occurs in high-profile national coal to gas work, hot water boiler with a vertical, drop out of microparticles of less infection, nitrogen oxides and other harmful gases and secondly smoke has also been oppression. Energy consumption is an important measure of navigation vertical hot water boiler, a good start to say a bunch of energy because of the impact of vertical hot water boiler together under research topic. After studying the relevant departments, the heat loss vertical hot water boiler consists mainly from two aspects: the proportion of full combustion air and flue gas emissions unreasonable heat loss. Flue gas exhaust heat loss can weaken the vertical installation of the tail water boiler fume heat recirculation means, or with more advanced features of the condensing boiler. The combustion air fully proportional unreasonable non-compliant summary: ordinary vertical hot water boiler based on ejector burner, causing the air-fuel ratio is no way to take the initiative to mobilize happen. A lot of hot water boiler is based on a vertical mechanical blower burner, resulting in unreasonable fuel ratio has the following several reasons: the main air-fuel ratio comprises unreasonable situation fall into two categories: When too much air will there are extra cold air is rich in thermal conductivity, resulting in increased energy use vertical hot water boilers, low energy consumption vertical hot water boiler; when there is insufficient air will cause appears insufficient to ignite the situation, causing low energy consumption vertical hot water boiler.

A fire tube boiler creates heat in pipes to heat the water surrounding the tubes, and the boiler vessel itself contains the water being heated. While this type of commercial boiler would be ideal for both low- and high-pressure steam, or for hot water applications, it is limited in the amount of pressure available.
