New stoves all setup run around $8-10,000. Before switching over, my gas bill was $3,500 per year at 60/gal. With it I also heat my domestic hot water (never a cold shower). I have been using outside woodstoves since 1995. What has been your experience with outdoor wood furnaces? When comparing outdoor wood furnaces to other wood heating methods, outdoor wood furnaces appear to be more efficient and reduce environmental impact, and proponents of outdoor wood furnaces claim a cleaner, safer, and more efficient heating system that will help everyone, not just the operator.
There has been much debate concerning outdoor wood furnaces and their cost, efficiency, and environmental impact. These include wood heat's impact on the environment, emissions, local disruption, and health problems. There are less desirable characteristics of wood furnaces that also need to be considered. Minimal loading is a convenience as some outdoor furnaces only require loading once or twice a day. Outdoor wood furnaces also have a thermostat control that keeps the heat at a constant level, which is sometimes difficult to achieve with a woodstove or fireplace. With the unit outside, smoke, soot, and ash are eliminated, and dryness is reduced in the buildings. Another benefit is cleaner building interiors. Safety is the most recognizable since these units are placed outdoors, there is less concern regarding fire and smoke hazards. Performance Parameter: Total Pressure, Flow, Power, Speed, Voltageĭ.We've found there are a number of benefits to the use of outdoor wood furnaces. Rotation Direction: Clockwise or Anti-clockwise, Viewing From Motor Sideģ. Fan Model and Name: Forced Draught Fan (FDF) or Induced Draught Fan (IDF)Ģ. It owns low vibration and reliable operation.Ĭustomers should note the following items when ordering:ġ. Having compact construction, the fan occupied small area. With immersion oil natural lubricating and no any other lubricant power system, the bearing damage and oil leakage caused by electric power cut will not occur.ĥ. The outer spherical sliding bearing has fine centering character. It Is convenient for customers to control the site noise according to their own requirement, i. The stiffener plate is reasonably arranged to the outer surface of the casing, which has good rigidity. Manhole is opened in three different directions, so that the important parts can be easily maintained and overhauled after the fan stop working.ģ. Split casing is convenient for the transportation and assembly. With flat performance curve and wide region of high efficiency, the highest efficiency can be 85% or above when the damper opens completely. Outer spherical sliding bearing is used for the fan, with water cooling system inside, so that the operating temperature can be kept under 75C.ġ. Considering the dust that contained in the conveying gas, reasonable wear-resisting treatment has been made to relevant part of the impeller.ĥ.
Meanwhile, for the main shaft and the motor, direct-connection drive of gearing coupling is selected, which results in many advantages, such as convenience in repairing or replacing the impeller, reducing the rotor weight and lengthening the bearing service life.Ĥ. The main shaft and the impeller hub disk constitute an unity. In order to ensure enough rigidity, integral forging is applied to the main shaft, i. Having been taken consideration of casing deformation caused by operating in thermal state, optimum matched clearance is ensured for all parts, to make the stable aerodynamic and mechanical performance reliable.ģ. Acoustic insulation structure is installed to the casing, with which the pneumatic noise can be ensured under 85 dB(A) according to the requirement of customers. During running, the on-off of the damper is controlled and operated by electric actuator.Ģ. Damper is adopted in the fan outlet for controlling the wind volume.
#Draft fan with draft control for owb series#
AL series of centrifugal FDF and IDF have such two structural types as single-suction double-support type and double-suction double-support type.
