NOVELTY - The manufacturing apparatus has a molded portion that crushes a water-containing wood chip for obtaining moisturized biomass fuel. The obtained moisturized biomass fuel is stored in a moisturized biomass fuel storage unit (22). A fuel supply unit is provided to supply fuel from fuel storage unit to a combustion unit, a heat exchange type warm water generation unit and a warm water storage unit. A moisturized biomass fuel pellet is provided to mix and inject crushed material of the water-containing wood chip into a silo-type hopper.    USE - Continuous warm water manufacturing apparatus used in agricultural facility.    ADVANTAGE - The wood type biomass fuel can be generated and exploited effectively. The temperature and humidity of timber can be controlled efficiently. The hot air can be generated during biomass process of wood chip. The utilization rate of fuel can be improved. The combustion efficiency of combustor can be improved. The generation rate of heat energy during burning of water-containing wood type biomass can be reduced. The temperature of the greenhouse can be controlled. The timber can be combusted economically. The drying temperature and humidity in silo can be adjusted for water-containing biomass fuel. The manufacturing cost of manufacturing apparatus can be reduced. The warm water can be produced efficiently. The resources of manufacturing apparatus can be saved.    DETAILED DESCRIPTION - The apparatus has fuel supply unit that supplies fuel to a combustion furnace. The fuel pellet is arranged at front-end of combustion furnace. A tamper regulator is arranged at inlet port of a fuel-supply silo for adjusting temperature of pellet. The front end of fuel supply unit is connected with the furnace. The air-blowing nozzles are arranged at destination edge of the pellet. A combustion plate is arranged at lower end of the pellet. The air is supplied to inlet port of the combustion plate. The diameter and length of furnace are set in specific range. The fuel supply unit of a silo system is arranged in the furnace. A hot-air distribution pipe is installed in the tank. A grate plate is arranged at upper end of a horizontal cylindrical combustion portion arranged in furnace such that combustion is raised within the grate plate. The grate plates are made of metal and ceramic. The air from an air nozzle is supplied on the grate. The wood chip is selected from one of the waste microbial-bed wood chip, coppiced timber, bush lot waste material, factory waste material, packing material, pruning branch, food processing waste material or particle board. The water content is set in specific range. The warm water generation unit is located in combustion portion. The pipes (17) are installed in multiple stages of water tank. The warm water generation unit is provided with a heating boiler function for generating warm water. A heat exchanger is provided with an exhaust-gas process portion for discharging exhaust gas (20) from furnace. The pipe is attached to a metallic pipe. The heat exchanger is connected with a hot-water boiler for heating warm water at the specific degree. The exhaust-gas process portion is provided with a dust collector for collecting dust contained in combustion exhaust gas discharged from the heat exchanger. The warm water storage unit is utilized for a vinyl greenhouse with certain volume. The volume of warm water storage unit is set in specific range.
