Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, d shap boiler and assesreis flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot water boiler of a 4.2MW for heating needs of the shopping center.
18tph SZS series condensing gas-fired steam d shap boiler and assesreis project for paper industryAs everyone knows, the corrugated paper processing industry has an increased demand for steam, which is the essential support for the production processes of presetting corrugated base paper, molding, gluing, etc., therefore, a steam boiler is one of the key facilities of corrugated paper manufacturing enterprises. Baixiang County Gem Paper Co., Ltd., as a subsidiary company of Jin Gem Group, engaged in manufacturing high strength corrugated paper with an annual output value of over 100 million yuan. The previous coal boilers of Gem Paper were facing the challenge of upgrading with the severer market competition and stricter national environmental protection policies. Gem Paper knew that the stable heat output of a steam boiler had a direct impact on the quality of corrugated paper. The company conducted contrastive analysis of multiple boiler suppliers and was attracted by ZOZEN with the advantages of stable running and energy-efficiency.ZOZEN tailored a complete set of solution for Gem Paper after thorough communication. Gem Paper ordered 4 sets of SZS series gas-fired steam boilers (SZS18-1.6-Q) to meet the requirements of their production lines. This series of boilers adopts the design of longitudinal double drums and " D " type chamber structure, the steam drum, the water drum and convection tubes form the convection heating surface. Big combustion chamber equipped with a low NOx burner effectively reduce the NOx as well as increasing the thermal efficiency over 98%; Boiler body uses the forced circulation in the high temperature area to make sure all heating areas can be cooled down and avoid vaporization. In addition, the feature of automatic operation realizes the unattended operation and save labor costs for Gem Paper.
Hazard Ultra-low-load operation of the d shap boiler and assesreis What? Coal-fired boilers is 70% to 100% of rated load, fuel gas boiler 60% to 100% of rated load. Ultra-low-load operation is deemed to run below this range. Then the ultra-low-load operation of the boiler harm What? Fuel gas-fired boiler factory and you came to talk about it! 1. difficult to guarantee the quality of steam: with the boiler load decreases, the steam temperature and humidity will be affected, in particular for a boiler with a superheater, boiler load is reduced, resulting in reduced exit steam temperature is difficult to maintain rated steam temperature, steam quality deterioration. When the superheated steam temperature drops below nominal, soda heating surface system conditions will enter the danger zone, when the load is low zui called technically permissible load. 2. boiler water circulation decreased reliability: fuel gas circulation usually natural circulation. Ultra-low-load operation, because a small amount of fuel into the boiler, the temperature drop across the furnace, the heated water wall weakening, boiler water circulation flow rate will be reduced, reliability is lowered circulation. 3. The rear of the boiler heating surface acid corrosion aggravated: Ultra load operation, the furnace temperature was decreased to varying degrees departments, the exhaust gas temperature will be reduced. It is easy to make the heating surface of the metal wall of cryogenic temperature below the temperature of the vapor *** sulfuric acid, sulfuric acid vapor condensation heating surface will be at a low temperature, resulting in low corrosion of heating surfaces. In summary, fuel gas-fired boiler ultra-low-load operation this issue, we can not be ignored.
