Detailed introduction

overall heat transfer coefficient of flue gases water in boiler

Industrial boilers can provide heating support for the processes of edible oil production such as drying/cooling, hot air baking, crushing/peeling, steaming and frying, etc. The long-time and stable operation of boiler can directly affect the edible oil products. Therefore, edible oil plants prefer to selecting high-quality, energy-saving and eco-friendly boilers in order to improve the production quality and efficiency and lower the boiler operating costs.

The boiler is a kind of special equipment and its export to the international market and competitiveness in the world lie in its conformity marks from international authoritative certification bodies. ZOZEN has extended its sales network from the entire Asia to Africa, Oceania, Eastern Europe, America and other regions over the years. ZOZEN also has obtained important international certifications such as ASME, PED, DOSH, IBR, and has been qualified for independent import and export of industrial boilers. Its various series of boiler products have been sold to more than 100 countries and regions around the world.

      Every pound of water in the hot gas converted to a liquid adds 1,000 BTUs into the boiler water. The dry flue losses and loss from the water vapour can be readily calculated if the amount of CO2 or 02 in the flue gas is known (this is used to calculate the dew point for the water in the flue gas and to determine the concentrations of the hot gas products) and the stack temperature is known.

      Corrosive flue gas is no longer a show-stopper for heat

      A significant amount of waste heat in flue gases remains untapped due to the limited applicability of metal heat exchangers under conditions where acid dew point corrosion can occur. The HeatMatrix polymer heat exchanger overcomes this limitation and enables energy savings by up to 5% in combustion processes and even up to 25% on dryers.
