direct efficiency of gas fired boilers heating

ZG has designed and furnished more than 25 units of HRSG direct efficiency of fired boilers heatings, with variant configurations of single, double, and triple pressure, natural circulation and forced circulation, vertical and horizontal arrangement. The HRSG is designed in modules, with full hanging structure for free expansion. The exhaust gas comes from gas turbines combusting heavy oil, light oil, natural gas, slug oil, and low HV fuels. At present, ZG can produce all these units of HRSGs for different kinds of industry. There are prospect of a very largo market and business opportunities for energy saving and environmental protection products under the national policy that putting energy and emission reduction in practice. ZG will make more contributions in this field.

The CFB direct efficiency of fired boilers heatings will replace typical pulverized coal (PC) units that are outdated and worn out. Combustion of high-ash anthracite in the CFB boilers is inefficient, requires considerable co-firing of natural gas and produces high SOx and NOx emissions. The important boiler design and performance parameters, such as furnace height, fuel and limestone sizing, solids recirculation rate, combustion efficiency and emissions performance, were developed using the results of high-ash anthracite pilot CFB testing.

Wuhan Yu Dahua Group Co., Ltd. is a cotton based, weaving, knitting and textile car decoration installation in one of the cross-industry, diversified and comprehensive export-oriented enterprise groups. 2017, the Group expanded production scale textile processing, the number of new production lines, the Group's original steam direct efficiency of fired boilers heating can not meet the growing demand of orders in urgent need of a new steam boiler purchase. When selecting vendors steam boiler, the boiler output device side fast sustainable high quality steam attracted, decided to cooperate with the fast boiler. Fast art by side to the user site needs analysis, to provide two integrally condensing gas steam boiler (WNS4-1.25-Y.Q).

Gas oil furnace pump selection and purchase points to consider: conducting oil furnace oil furnace gas this kind, because it is one of the website product, so the knowledge and understanding of the product, at least, should achieve a comprehensive and specifically this level, so as to learn to have a good effect. Moreover, this is the basic requirement, so the following, it is better to proceed immediately, thereby, improve our learning efficiency .1. Gas oil furnace, the use of the pump, what good measure? Gas oil furnace on the direct efficiency of fired boilers heating, a pump energy saving, the pump energy is recommended to use four, because it can be recycled flue gas temperature. Further, on the main circulating pump, the flow rate can be appropriately increased, thereby improving the heat exchange efficiency inside the boiler, in turn, to achieve air and save energy both goals. 2. The expansion tank of gas conducting oil furnace, the oil level is much more appropriate? In addition, its purchase, to pay attention to what? Gas oil furnace in the expansion tank, the appropriate oil level, is two-thirds the height of the expansion tank, and, to ensure that overflow does not occur the problem. And the purchase of products, in general, is to consider the use area, manufacturers and service qualification, and the use of these requirements and the environment. Through them, to choose the right products.

is high efficiency gas boiler worth the investment? what's

A high efficiency gas boiler (>90%) must have the flue gas condense in order to achieve that efficiency. The flue gas will only condense when the return water temperature is 120 degrees or less. An ordinary system has return water temperature much higher than this, because this is the temperature for which your radiators are sized (typically 180 supply, 160 return).

Efficiencies in gas-fired boilers have raised over the past decade from the low 90% AFUEs to upper nineties. An AFUE percentage rating is the amount of energy produced by the system to be used for heat. The remaining percentage dissipates or is exhausted out the flue. For example, a 92% AFUE rated gas boiler will use energy (gas/oil) to generate 100% heat (boiler rated BTU/h).
