safe and reliable steam boiler with ce asme

Our emphasis on increasing green, local governments also boiler operation produces nitrogen oxides and smoke emission requirements become more stringent. Fast boiler followed by the national trend of development, deepening of cleaning boiler product design and development. Lulu as a representative of business development of the national beverage, and hope to find a set of boiler energy conservation and clean in one, for drink production process of fermentation, sterilization, drying, curing and other processes. After many visits and market research, in October 2017 and entered into boiler fast boiler purchase contracts, purchase two 10 tons of steam and a whole 20 tons of steam condensing safe and reliable steam boiler with ce asme. The two sides this cooperation is the other quality fast condensing gas boiler highly recognized, has proved a powerful strength fast boiler in the boiler production and service of gas condensate from the side.

So, condensing heat recovery waste heat recovery boiler is how to achieve ultra-high thermal efficiency it?

1, different structures with ordinary gas-fired boilers, waste heat recovery condensing gas boiler addition of the condensing heat exchanger, economizer and air preheater, these facilities are recycled flue gas latent heat made adequate preparations.

2, burner structure is also different. Waste heat recovery boiler of condensing gas burner uses a split combustion engine, and in advance of the combustion air is heated by the air preheater, the heat released by combustion of the fuel is directly supplied to the boiler, to the combustion air need not be provided.

3, the condensing heat exchanger select stainless steel finned tubes, heat transfer rate is more than five times the ordinary boiler, heat better, longer life.

4, gas condensing heat recovery boiler also propose solutions to the nitrogen oxide emissions through the selection of target quality low NOx combustion engine to achieve low nitrogen emissions, is a pioneer in environmental protection.

What are the advantages of condensing low nitrogen pressure boilers

Condensing low nitrogen pressure boilers are widely used in various civil and commercial places, such as compound villas and commercial hotels. Its operation is convenient, using plc controller, configuration level is higher, only touch screen button can be used to control the whole operation of the boiler, so the use of this kind of boiler after the liberation of manpower, but also can reduce the cost of manpower care. So what are the advantages of condensing low nitrogen pressure boilers?

1. long service life. The condensing low nitrogen pressure boiler can be used in all kinds of environments, and it can also be used in the north of China. It has the function of anti-freezing protection, when the water in the boiler is lower than the set value, it can automatically run and heat, and automatically stop when the water temperature matches the agreed temperature, so it can protect the equipment itself and its auxiliary equipment. 2. The anticorrosive pressure boiler is not only scientifically designed, but also optimizes the operation of each system. It can not only prevent low temperature, corrosion, but also avoid the cold impact on the wall of the furnace, so its durability is strong and its service life is longer.

2. the use of safety (overheating, water shortage alarm) this pressure boiler design has taken full account of the use of safety issues, set up a number of safety gateways. It has the function of overtemperature alarm, that is, when the water temperature is super high, it will automatically stop heating, and carry on the overtemperature alarm, only need manual reset after the fault is completely relieved; It also has water shortage protection function, can automatically stop when water is short and alarm, prevent dry burning.

3. high thermal efficiency (full use of energy, energy saving) the domestic professional pressure boiler has a larger heating surface, its heat transfer efficiency is high, can maximize the enhancement of heat transfer effect. In addition, the effective outer protective layer of the pressure-bearing boiler is good, the glass cotton is used to ensure the temperature is constant, and the heat loss of the boiler is relatively small to prevent a large amount of heat dissipation, which can make full use of energy and realize high efficiency and energy saving.

A: the adaptability of the gas sources 1: Natural gas must depressurization gas regulator and gas regulator, the pressure before the Burner selected to meet the requirements before entering the burner, in order to work properly. 2: automatic adjustment operation of the boiler performance requirements: since a large gas consumption of the gas boiler, gas boiler as possible in order to reduce impact (sudden pressure regulator after the gas lift system during starting or stopping, sags ), controlling the gas boiler during operation must meet the following requirements: start (1) gas boiler must be adjusted to start at the minimum load of 30% (the rated load); (2) a gas boiler must be gradually reduced before shutdown load, rated load to be reduced before shutdown when the valve closes the solenoid 30%; (3) boilers can be automatically adjusted according to the boiler heat load during normal operation of the actual output stage operating conditions, automatically increasing demand for large Great demand hours automatically reduced, self-sustained heat balance of supply and demand, greatly reducing the number of start and stop the boiler; when reduced to 30% or less of the rated load, heat production is still greater than the output of the boiler, before proceeding down. (According to relevant statistics, the explosion occurred in the gas boiler start-up and shutdown of these two periods that occurred during ignition and fire in., A small gas boiler gas explosion has occurred 2/3 during ignition) (4) is provided above the automatic adjustment function is particularly important when a voltage regulator with many boilers, the boiler can start to avoid pressure fluctuations caused by stopping overpressure safety device or system boiler gas low-voltage protection action, the normal operation of the boiler shutdown. Two: for gas safety, gas boilers must have security facility 1: ignition control system for a gas boiler before ignition, purge the furnace and flue must be carefully excluded combustible gas furnace may be accumulated. A reasonable ignition process control systems to cope with the ignition process is automatically controlled fan only after the completion of furnace cleaning tasks to perform ignition; only when the ignition flame has been established (confirmed by a flame detector), and after a predetermined time has elapsed, a control valve main burner to open; ignition flame is automatically extinguished after a predetermined period of time; when the main flame could not be ignited within a predetermined period of time, the main burner can be automatically and quickly turn off the ignition flame is extinguished while gas boiler ignition procedures are generally monitored and controlled by a program controller. Control of the ignition process, the ignition before the total ventilation should be not less than 3 times the total volume from the furnace to the chimney population. 2: Safety Devices gas boiler is run prevent excessive wind load caused by a low flame, combustion automatic adjustment device should be installed on each boiler, intake air volume and gas supply gas boiler control linkage.
