coal fired industrial hot water boiler seller
The fields of use vary for different types of water tube boilers. CBM oil and gas water tube boiler is a double-drum type boiler with a capacity ranging from 4 to 80 tons. The szl series water tube boiler is a boiler that can adapt to a wide range of fuels. The boiler can burn a variety of biomass and coal fuels. The water-cooled wall structure can be used to control the furnace exhaust temperature by increasing or decreasing the heating area of the water-cooled wall to ensure sufficient combustion. CBM also produces circulating fluidized bed water tube boilers, corner tube boilers and so on.

Fangkuai boiler operation advantages 1, large font display water temperature, easy to grasp the boiler and system operation conditions, water temperature from 10 ℃ to 90 ℃ can be set at will, the boiler automatically to the system heating or to provide the user with hot water for bath. 2, the control system controls the start and stop of the circulating pump according to the furnace water temperature, when the furnace water reaches the set upper water temperature, the hot water circulating pump starts, and the hot water circulating pump stops when the water temperature is lower than the set lower temperature. 3. The horizontal gas-fired bath boiler is a three-way full wet back structure. It adopts the design of large furnace and coarse smoke pipe to increase the radiative heat absorption of the furnace and effectively save energy and reduce consumption. Use of threaded smoke pipes and Waveform furnace tank, greatly enhanced the heat transfer effect, greatly saved fuel consumption. 4, the whole machine is also equipped with overheat protection (when the furnace water temperature is super high, the burner automatically stops working and beeps to alarm, and the secondary overheat protection (when the boiler shell temperature exceeds 105 ℃, the secondary circuit is automatically cut off), When the boiler water is lower than the very low water level, the boiler stops working and gives a buzzing alarm), and the boiler leakage protection (the control system detects the electrical leakage, and when the short circuit is short, it will automatically cut off the power supply). 5, the boiler is designed according to the normal pressure structure, the boiler is in a pressure-free state, there is no danger of safety. Use of advanced centrifugal glass cotton multilayer protection Temperature, famous white color steel plate for outer packaging, less heat loss, beautiful anti-rust.
01. The gas-fired boiler should pay attention to the following points during operation: (1) the gas-fired boiler does not allow positive pressure combustion or smoke injection in the furnace, because it is easy to burn out the coal hole cover. (2) the bottom floor of the gas-fired boiler shall not be watered up to prevent damp corrosion. 2, gas-fired boiler operation every 2 weeks, should be checked. 3, gas-fired boiler operation every 3 months after 6 months, the furnace should be shut down for comprehensive inspection and maintenance. (1) check the gas boiler inside and outside, such as the welds of the compressed part, the corrosion phenomenon inside and outside the steel plate, if found serious defects should be repaired in time, if the defects are not serious, it will be repaired the next time the furnace is shut down. If any suspicions are found but do not affect production safety, records should be made for future reference. (2) after inspection, the boiler primer may be coated on the surface of the water to prevent corrosion. 4, gas-fired boiler and boiler base paint at least once a year. 5, gas-fired boiler maintenance method: dry method and wet method, shut down for more than one month, should adopt dry maintenance method, shut down for less than one month can be used wet maintenance method. (1) dry maintenance method: after the boiler stops the furnace, put away the boiler water, thoroughly remove the internal dirt, rinse it out, dry it in the furnace with a slight fire (pay attention not to fire), and then it will be 10 mm in diameter and 30 mm in diameter. The small lump of quicklime is divided into plates, placed in the pan, without contact with the metal, and the weight of quicklime is calculated at the volume of 8 kg per cubic metre of the drum, and then all manholes, hand-holes, pipe valves are closed, Check every three months, if the quicklime is broken, replace it, and remove quicklime and tray when the boiler is re-in operation. (2) Wet maintenance method: after the boiler stops the furnace, it gives out the furnace water, thoroughly removes the internal dirt, rinses it, reinjects the treated water to the full, heats the furnace water to 100 ℃, lets the gas from the water drain out of the furnace, and then closes all the valves, Protection is not allowed in cold climates Wet curing method, lest the furnace water ice damage the boiler.
Shutdown four tons of gas boiler steam boiler shutdown and maintenance of fire into pressure shutdown, normal shutdown, emergency shutdown. A pressure fire fire shutdown shutdown pressure applied to temporarily stop the supply of steam, the boiler is shutdown pressure hot standby state. 1, before the pressure reduction appropriately to fire the boiler load, and according to the length of the seam thicker shutdown time, (up to 200mm) to accelerate the speed of the grate, the grate is stopped when rotated about 1.5 meters from the coal seam to the shutter. 2, stop blowers, blower suitably adjusted flap subsections, relying on a lean-burn natural ventilation is maintained. 3, the sewage, to allow the water level in the boiler water level. 4, Yang fire regularly, to prevent rotation of the furnace grate extinguish the fire bed. Young fire first before sewage water, then rinse water level gauge. II. Normal shutdown Normal shutdown for heating period ends, boiler pour fire into the buck repair or maintenance. 1, make a record before shutdown problems in operation, so that after the shutdown process. 2, the coal bucket coal memory runs out, the amount of toner to reduce the wind. 3. Stop the blower, draft fan stop and then the opened door grate ash. 4, after the steam supply is stopped out, the boiler to the boiler water to maintain a high level. 5, close the main steam valve, if the pressure rises to open the air exhaust valve suitable pressure relief. 6, stop the water supply to the boiler and economizer attention to monitoring changes in water temperature, open return pipe if necessary. 7, 4 to 6 hours after the furnace fire bed down exhausted, continued rotation of the cooling grate. Throughout the boiler throttle, the door should be kept closed. Allowed to naturally cool. 8, appropriate to open the pump, the boiler water and sewage. When the pressure drops to zero, open the air valve. 9, when the boiler water temperature is below 70 ℃, boiler water can be exhausted. Shutdown is complete. 10, less than 24 hours during shutdown. Avoid Shutdown cooling process, step-down too fast. Third, emergency shutdown emergency shutdown applies to the boiler accident, g combustion equipment damage, furnace or boiler structure collapsed wall is red-hot, a serious threat to the safe operation of the boiler when; h boiler pressure parts found serious distortion, leakage. when i found flue gas explosion or secondary combustion, boiler and seriously endanger the safety of operating personnel;; when endanger the safety of operation.. the safe operation of the boiler j endanger other unusual circumstances when. 2, the emergency shutdown procedures to immediately stop a blowing coal and reduce the wind; B rotates quickly grate, the pour slag pit coal or sand, wet ash coal burning fire to extinguish. , but not to the firebox water;. c boiler air valve, the relief valve opens quickly exhaust the steam pressure is reduced;. d after the fire goes out, stopping fan, opening the ash door and door, promote air circulation accelerated cooling; 3, emergency shutdown Notes a. when an accident and emergency shutdown due to lack of water, boiler feed water is strictly prohibited to, and shall not be such as to open the air valve or exhaust valve work on preventing boiler from sudden changes in temperature or pressure to expand accidents;. b when filled with water due to an accident and emergency shutdown, should immediately stop the water supply, reduce combustion, open the drain valve and drain, due to lower the water level, while opening the main steam pipe, the sub-cylinder and steam traps mother tube, water and prevent steam pipe with a large number of water hammer occurs. c. emergency shutdown operation to ensure the safety of the main event of an accident to calmly deal with, timely reporting, and make relevant records in the "log table boiler." d. Whether shutdown any case, we must maintain timely contact with steam departments.
