The use of gas-fired modular boilers in office buildings, what are the selection standards?
How to combine energy-saving, environmental protection and intelligence in gas-fired boiler, the fast-speed boiler has invested a lot of capital and energy, and put forward the boiler equipment-gas-fired modular boiler, which accords with the above-mentioned conditions.
Gas-fired modular boiler means that multiple gas-fired boilers are set up by the joint control system, according to the dynamic parameters such as the set-up heating temperature curve, and referring to the variation of temperature difference inside and outside the room or the change of their own needs, intelligent automatic judgment of start-up. The number of boiler operation stations that stop operation and realize the near-unattended operation mode can also avoid the waste of resources.
Centralized office buildings in the selection of hot water and heating of the thermal equipment, gas-fired modular boiler is no better.
Fangkuai Boiler for you summed up several gas-fired modular boiler selection standards for you to more comprehensive understanding of this type of boiler, and combined with their own needs, reasonable judgment.
First, the operation cost is high and low
"Module", the equivalent of a single large boiler into a number of small boilers, in the number of "simple parallel combination" can achieve different steam tons of demand. The modular design structure determines the three characteristics of the boiler.
1, each boiler is a backup, once a single boiler sudden failure, other boilers can start immediately, the impact on heating is very small.
2, the expansion of capacity is good, and the demand for heating and other heating loads in many office buildings will change in different seasons, and the selection of modular boilers can perfectly solve this situation by increasing or reducing the number of boilers at any time. Achieve a smaller investment to meet the demand.
3, the boiler room infrastructure requirements are not high, can greatly reduce the cost of infrastructure investment.
II. Low nitrogen emissions
Many office buildings are built in the urban center. With the stricter emission standards of air pollution in our country, many cities have implemented coal ban or ultra-low nitrogen emission requirements. By using the patented wing heat transfer technology, nitrogen oxide emission can be as low as 18 mg / m3, which can meet the boiler emission standards in all regions of China.
Third, the safety index is high and low.
Centralized office building general staff are more dense, once a sudden disaster, the consequences are unthinkable.
The square fast boiler can be equipped with intelligent remote monitoring cloud service system for each boiler, and professional supervisory personnel observe the operation of the Fangkuai Boiler in our country all day, and once the emergency situation is discovered, the early warning device is started remotely immediately. And notify users online, killing the danger in the cradle.
The above are the office buildings for you to select gas-fired modular boilers, I hope you can help you better choose the appropriate boiler for your business. If you have any other questions about the boiler, you can call our technical engineer's hotline directly, and we will do our best to help you.
The difference between condensing boiler and ordinary boiler
There are so many kinds of boilers on the market, and the price difference is very big, have you already felt dazzled? There are also a lot of people who hear sales people talk about condensing boiler frequently, so, what is condensing boiler, eh? What's the difference between it and an ordinary boiler? Today, we will introduce you to this boiler's elite-condensing boiler, a two-minute understanding of the difference between a condensing boiler and an ordinary boiler.
One, what is a condensing boiler
Boiler in furnace is a kind of boiler which adopts condensing technology to improve the thermal efficiency of boiler. Condensation technology refers to the absorption of sensible and latent heat released from fuel combustion by using condensing waste heat recovery device inside the boiler. The sensible heat is mainly the high-temperature flue gas produced by boiler combustion, and the latent heat is mainly the heat released from steam condensation. Don't underestimate this amount of heat. Condensing boilers are 15% to 25% more efficient than conventional boilers.
Second, the difference of thermal efficiency
It is also mentioned that the thermal efficiency of condensing boiler is higher than that of ordinary boiler, so we will talk about the thermal efficiency of condensing boiler. Why focus on thermal efficiency? is thermal efficiency so important? Of course it matters! The high and low thermal efficiency of a boiler directly determines the energy consumption of this boiler. In other words, the thermal efficiency is related to the money in everyone's pockets.
First of all, the thermal efficiency of ordinary boiler can only reach 85% / 91%, while the heat efficiency of condensing boiler is generally higher than 100%, and the heat efficiency of condensing boiler produced by square fast boiler factory can even reach 108%. This extra 10% / 20% comes from the use of condensing technology to give full play to the sensible and latent heat of boiler operation. The temperature of flue gas discharged from ordinary boiler is very high. The steam produced by fuel combustion is discharged from flue gas, and a large part of heat is lost. The condensing furnace reclaims this part of the heat and reuses the reclaimed water from the heating system to raise the boiler's exhaust temperature by lowering the exhaust temperature. Thermal efficiency. Under the same amount of gas consumption, the lower the return water of the heating system, the more heat recovered by the condensing furnace, the higher the thermal efficiency of the boiler.
Third, the difference of scale treatment methods
Condensing boilers are less likely to scale than ordinary boilers. In order to improve the heat transfer efficiency of boiler, many boiler manufacturers adopt fine heat exchanger and water pipeline, and the water quality is hard, so it is easy to form scale in the pipe. Scale condensation is easy to cause pipe clogging to damage the equipment, which increases the cost of boiler maintenance at the later stage. The condensing furnace adopts premixed combustion technology, which is a large pipeline waterway system, which is not easy to be structured. Therefore, the condensing boiler has not high requirement for water quality.
IV. Differences in environmental protection
Condensing boilers are more environmentally friendly than conventional boilers. When the gas burns in the furnace, it produces a lot of carbon dioxide, nitric oxide and a little sulfur dioxide. These burning substances will cause damage to the air environment with the emission of smoke into the atmosphere, which is more intuitive is Greenhouse Effect and acid rain. While condensing boiler condenses steam in flue gas, the emission of harmful substances in flue gas also decreases. From the point of view of environmental protection, condensing boiler is more worthy to be used than ordinary boiler.
The difference between price and service life
In contrast, the condensing boiler has so many advantages, the price is certainly higher than the ordinary boiler. After all, condensing boiler is also called a combination of technology and quality of the elite. But the price is certainly expensive, in addition to environmental protection and energy-saving condensing furnace service life is also higher than ordinary boilers, more cost-effective.
Boiler is an important source of power to promote the production of enterprises, the purchase of high-quality boilers is only a beginning, in order to ensure the long-term stable use of boilers, materials, auxiliary equipment and after-sales service must be guaranteed. Therefore, we suggest that when purchasing boilers, we must examine the quality of boilers and boiler manufacturers from many aspects, and avoid problems in the later stage.
