In boilers, China wholesale boiler economizers are heat exchange devices that heat fluids, usually water, up to but not normally beyond the boiling point of that fluid. Economizers are so named because they can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler, thereby recovering more useful enthalpy and improving the boiler's efficiency. They are a device fitted to a boiler which saves energy by using the exhaust gases from the boiler to preheat the cold water used to fill it (thefeed water).
1. newly designed economizer with higher efficiency.
2. cast iron material which could resisit for higher temperature.
3. take fully use of the exhause heat from the boiler, increase the feeding water temperature, which could help to imporve the boiler efficiency.
4. with long working life.
5. capacity range from 0.5t till to 40t.

We are assisted by our truly skilled and seasoned professionals in manufacturing a precision-engineered range of Wood Fired Steam Boiler. The offered boiler is any closed vessel exceeding capacity which is used expressly for generating steam under pressure. Our provided boiler includes any mounting or other fitting attached to such vessel, which is wholly or partly under pressure when steam is shut off. Being fired with oil or gas, these boilers are optimized for energy efficiency and superior conversion of energy.
With the support of our multi-talented professionals, we have established ourselves as a leading manufacturer, exporter and supplier of quality-assured steam boiler. We manufactured these offered range of products keeping in mind the varied requirements of different industries. In this regard, we use ultra-grade metal and other required raw material. Adding to that, before finally approving these boilers, they are tested according to different quality parameters set by the industry. Feature: Easy maintenance Cost effective Smooth finish High efficiency Convenient outlets Specification: Material used: mild steel, stainless steel Pressure: high pressure Fuel: electricity
The boiler is a three-pass, fire-tube steam boiler made by Finnish Ahlström Themoflow in year 1990. The boiler has max operating pressure16 bar with 205 C steam temperature and it is equipped with exhaust gas economizer for preheating incoming feed-water and modulating heavy fuel oil burner. It's has a large 15.2 m3 water volume which allows big momentary changes in load. Other benefits include simple structure, long operating life, reliability and ease of service and maintenance. The boiler is in good operational condition. Feed water pumps and feed water tank with aerator are available for separate request and price. Technical Data: Manufacturer: Ahlström Thermoflow, Kaarina Manufacturing year: 1990 Capacity: 3.3 MW Water volume: 15.2 m3 Steam characteristics: Max 16 bar, at 205 C temperature, saturated Oil Burner: Weishaupt Monarch RMS 50/2 A - ZM (YOC 1990) Oil feeding: 140 - 490 kg/h.
