Abstract

Summary of the invention which appears on the advertisement page ReadFile:This invention involves a high-heating furnace under normal atmospheric pressure for rubber wood consisting of a biomass cyclone furnace (Furnace) (1) working with the system. Semi-automatic fuel feed control (2) There is a heat exchanger (3) located above the cyclone biomass furnace (Combustor) (1) to support the hot flue gas (HotFlueGas) from the furnace to discharge into the cyclone. Outside (ExternalCyclone) (4) and some hot exhaust (HotFlueGas) flows into the return pipe (12) into the rubberwood furnace (5) to mix with the hot air (HotFreshAir) from the biomass cyclone furnace. (Furnace) (1) Forming hot air (HotFreshAir) at a higher temperature for the production of rubber wood that has undergone heat treatment (ThermalWood) with a rubber wood oven (5) looks like a container (Container). Connected to biomass cyclone furnace (1) via air duct system and valve system.

Claims (1)

Claims (all) which will not appear on the classifieds page: 1. High temperature wood dryer under normal atmospheric pressure for rubber wood consisting of a biomass cyclone furnace (1) working with a semi-automatic fuel feed control system (2) with a heat exchanger. (HeatExchanger) (3) located above the biomass cyclone incinerator (Combustor) (1) to support the hot exhaust (HotFlueGas) from the furnace to be released to the external cyclone (ExternalCyclone) (4) and collect dust, flakes at May be mixed with hot exhaust gas. There is a rubber wood oven (5) in the form of a container (Container) connected to the biomass incinerator cyclone system (Furnace) (1) through the air duct system and valve system (Valve) biomass incinerator. Cyclone system (Combustor) (1) The internal area is a combustion chamber used to burn solid biomass fuels (SolidBiomass) such as wood chips, chopped wood, sawdust, and then bring the heat from the combustion to be useful in the drying of rubber wood under the heat. The normal atmosphere is characterized by the cyclone biomass furnace system (Furnace) (1), which is a vertical cylindrical furnace with a capacity of 400 kilowatt hours (kwth) made of thick steel exterior, heat-resistant paint sprayed on the inside, made of refractory bricks. The light at the bottom of the stove has a hole for air distribution (FreshAir) from the outside. To the furnace and support the hot and humid air (WetHotAir) to mix with a blower (Blower) size 2 horsepower (HP) draws air into the firing room, rubber wood oven (5), contains 300-500 cubic cubes of raw wood. ft (ft3) The wall is double-layered, the outer wall is corrugated steel, the inner wall is lined with stainless steel sheets, there is a gap of 1.5 inches between the outer wall and the inner wall, filled with asbestos. At the bottom of the rubber wood oven (5), there are 3 hot air pipes (6), diameter 20 cm, length 260 cm, placed parallel to the length of the oven, 3 pipes to release the hot air (FreshHotAir) into the oven below. Blower (Blower) size 5 horsepower (HP) has a gap (SafetyHole) size 50X50 centimeters, a steel sheet that can break and come off first if high pressure occurs inside the oven, semi-automatic fuel feeding control system. (2)Installed on the side of the biomass cyclone incinerator(Furnace)(1)consists of ProgrammableLogicController (PLC)(7) receiving temperature value from temperature sensor (8), amount 2 The point is the wood incubator inlet temperature and the wood incubator internal temperature value for processing and issuing control commands in Inverter (Inverter) (9), a number of functions to determine the rotation of the motor (10) size 1 horsepower (HP) a certain amount to power a screw feeder (ScrewFeeder) (11) serves to feed fuel. Enter the combustion chamber where the working system uses three-phase (3-phase) voltage 380 volts (Volt) heat exchanger (HeatExchanger) (3) looks like a wall-and-tube heat exchanger ( ShellandTubeHeatExchangerDesign where cold air (ColdFreshAir) is contained within many small tubes serves to exchange the heat from the hot fluegas of the biomass cyclone furnace (1) until it becomes HotFreshAir. Rubber wood oven (5) through the hot air discharge pipe (6) with a blower (Blower) size 5 horsepower (HP) hot exhaust (HotFlueGas) from the biomass cyclone furnace (Furnace) (1) some inflow. To the suction pipe (12) into the rubber wood oven (5) to be mixed with the hot air (HotFreshAir) from the biomass cyclone furnace system (Furnace) (1) to form hot air (HotFreshAir) at a higher temperature. For the production of rubber wood that has been improved by using heat (ThermalWood) has a circulation system (Circulation) hot and humid air (W etHotAir) produced after the wood drying process inside the rubber wood oven (5) which floats through the conduit at the top of the rubber wood oven (5) into the HeatExchanger (3) before being sucked up. Back into the ground area of the biomass cyclone incinerator (Furnace)(1) used to mix with the incoming air (FreshAir).
