Abstract

------15/03/2018------(OCR) Page 1 of 1 page Summary of Invention high efficiency boiler for burning low quality fuel which the boiler is separated out of the combustion chamber To increase the distance (Free board) of the hot air to exchange heat with the pipe wall. Furnace as much as possible and reduce the temperature of the hot air before entering the exhaust pipe set appropriately. as a protection against damage at the exhaust pipe set inside the boiler The design of the heat exchange tube system inside the boiler is The straight pipes are bent outside the boiler wall to simplify and reduce the time in case of pipe replacement. Problems with pipe leaks due to service life For parallel flow of hot steam and steam pipes The second set of pipes to reduce the surface temperature of the second set of pipes, to extend the service life of the pipes. The boiler is designed to have an open lid at the hot air pipe between the exhaust pipe and the energy-saving pipe set to help reduce the cool down time inside the boiler. in case of stopping the machine for Repair energy-saving hose kits or repair air heater hose kits in case of hose leaks. and also has an open lid that The hot air duct area between the air preheater and the static rain catcher to reduce Cool down time within the static rain catcher in case of stopping the machine for Repair the static rain catcher set. which additional systems and equipment in the production process of the boiler as mentioned above will make The efficiency of the boiler is increased by approximately 2 to 3 percent and the downtime for repairs is reduced. Maintenance of the boiler due to the design that there is an air inlet at the hot air pipe between the exhaust pipe set and the pipe set. energy saving and at the hot air duct between the air preheater and the electric rain catcher. Anti-static and the design of the pipe fitting inside the boiler is outside the furnace wall ------------ Revised 24/11/2016 High efficiency boiler for burning low-quality fuel which the boiler will separate from the combustion chamber to increase the distance (Free board) of the hot air to exchange as much as possible to heat the furnace wall and reduce the temperature of the hot air before entering the exhaust pipe set to prevent damage to the exhaust pipe set inside the boiler The design of the pipe system for the exchange of The heat inside the boiler is a straight tube type with the elbow outside the boiler wall for easy and lower Time to cut and replace pipes in case of pipe leaks due to service life For parallel flow of hot steam and steam at the second set of steam pipes to reduce the surface temperature of the second set of steam pipes. not to be too high to prolong the service life of the pipe The boiler is designed with an open lid at the hot air duct area. Between the exhaust pipe set and the pipe set of energy-saving equipment to help reduce the time to cool down (Cool down) inside the boiler. In case of stopping the machine to repair the energy-saving equipment pipe set or repair the pipe set Air heater in case of pipe leaks And there is also an open cover at the hot air duct area between the air preheater ducts. With an static dust collection device to help reduce the temperature (Cool down) within the static dust collection device. In case of stopping the machine to repair the static dust collection device which additional systems and equipment in the production process of the boiler as mentioned above will make The efficiency of the boiler is increased by approximately 2 to 3 percent and the downtime is reduced to Maintenance of the boiler due to the design of the air inlet at the hot air pipe between the exhaust pipe set and the set. energy-saving equipment pipe and at the hot air duct between the air preheater and the capture device. Static dust and the design of the pipe fittings inside the boiler are outside the furnace wall. ---------------------

Claims (1)

Disclaimer (all) which will not appear on the advertisement page: Amendment 02/11/2018 No disclaimer ---------- ------ 15/03 / 2018-- ---- (OCR) Page 1 of Number 1 Page Terms 1. High efficiency boiler. For low-quality fuel combustion, it is characterized by an inlet (1) which is connected to the combustion chamber using a high heat resistant soft joint consisting of a first and second flow channel (2), the top Install drums (3) for condensation inside the furnace wall tubes, the bottom portion of the first and second flow channels, respectively, for carrying part of the heavy ashes of the channel. The second flow is equipped with a second (7) conduit, which is piled underneath the dug. The first set (6), where the steam entering the second set of conduit (7) has a parallel flow direction (8) with the hot air to reduce the temperature of the second set of conduit (7). The first (6) air hose set is connected to the energy-saving pipe set (10). Installed vertically By air preheater (12) connected to the trap device An electrostatic dust trap (14), which is at the bottom of the ash port (15) and a connection pipe between the suction fan (16) and the static dust collector (14) to extract the heat from the chimney (17). ) Or return to the incinerator It is burned via the hot return pipe (18). 2. High efficiency boiler. For the burning of low-quality pesos According to claim 1, which is the heat exchanger of the first (6) intake manifold, the second (7) set of pipe fittings Energy saving (10) and air preheater (12) inside the boiler is a straight pipe and is bent. Outside the boiler wall. 3. High efficiency boiler. For the burning of low-quality pesos According to claim 1, the heat pipe area between the first (6) and the energy-saving pipe set (10) has two open covers (9) to reduce the temperature reduction time. High-performance water For the burning of low-quality pesos According to claim 1, the heat pipe area between the air preheater (12) and the static-static dust collector (14) has an open cover (13) to reduce the temperature reduction time -----. ------- Edit 24/11/2016 1.High efficiency steam boiler For low-quality combustion of fuel, it consists of a separate boiler (1) from the combustion chamber. To increase the distance (Free board) of the hot air, exchange the heat with the furnace wall pipe as much as possible. To reduce the hot air temperature before entering the steam pipe set properly, this is to prevent damage to the steam pipe set inside the boiler. The heat exchanger (6), (7), (10) and (12) piping systems inside the straight-tube boilers and their elbows are outside the boiler walls. Parallel (8) flow of hot air and steam at the second set of steam pipes. To reduce the temperature of the pipe surface, the I Dong set The second set is not too high, extending the service life of the flap pipe (9) at the heat pipe area between the units. Exhaust pipe and pipe set, energy saving equipment To help reduce the time of cooling down (Cool down) inside the boiler. In case of stopping the machine to repair the pipe assembly, energy-saving equipment, or repair the pipe set Preheat air in case of pipe leaks. Open cover (13) at the area of the hot air duct between the air preheater tube set and Electrostatic dust collector To help reduce the time to cool down (Cool down) inside the device to collect static dust. In case of stopping the machine to repair a static dust collection device ---------------------
