Wholesale Coal Fired Hot Water 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.

Fast boiler has been to uphold the "mold character, and create boutique" business philosophy, after learning of the status of the state forest mountain elementary school, we are non-stop, quickly prepare a large number of teaching supplies, to the mountains in order to improve children's education hardware conditions positive contribution. In order for children to drink purified water clean and sanitary, after the group discussion after deliberation, determined to provide six sets of water purification equipment and pipeline machine. Teachers and students by means of this device can drink safe water purification, we can say that they know how these "water" next to the Red Flag Canal precious. Watching the children line up smiling face after the contact of water, we all feel distressed bursts.

Run chemical plant boiler problems that may arise is what chemical plant boiler operation possible problem is? There are two main chemical plant boiler evaporation: evaporation and rated maximum continuous evaporation. When the chemical plant boiler load is higher than the maximum continuous evaporation, it indicates the operating force or overload. The following problems may occur super-load operation: Main results are as follows: (1) due to increased fuel consumption, furnace volume heat load increases, the furnace temperature and furnace flue gas outlet temperature, resulting in the superheater and reheater the superheated steam temperature and wall temperature, and must therefore be strictly monitored and adjusted. Try not to let this time overheating. Coal furnace, furnace volume due to the increased thermal load, increasing the likelihood of slagging. (2) the flow rate of chemical evaporation apparatus system working fluid increases, the flow resistance is increased, it is not conducive to water circulation. Therefore, we should pay particular attention to the monitoring of the water cycle bad area. (3) the pressure differential between the drum and the superheater outlet flow increases as the working fluid and superheater flow resistance increases, so that the pressure of the steam drum and headers increases, the strength of these components must be considered . Space volume load (4) the steam drum, the load increases the evaporation surface, saturated with water vapor would increase, thus affecting the quality of steam. (5) chemical plant boiler safety valve Total displacement designed according to a maximum continuous evaporation. If the chemical plant boiler overload, once the sudden load shedding, the safety valve will not fully open, the steam pressure can not be reduced quickly. At this point, it is necessary to ensure the safety of the boiler by chemical vapor released into the air exhaust valve. (6) With the increase of the amount of air required for combustion and the amount of smoke produced, once sufficient air supply, the air volume is insufficient, the chemical conditions affecting the combustion boiler, increasing the likelihood of slagging; In addition, since the flue gas velocity the increase in fly ash increased the degree of wear of the heating surface. (7) during operation, the exhaust gas temperature rises, the exhaust gas heat loss; shorter residence time in the furnace the fuel, incomplete combustion heat loss of mechanical and chemical incomplete combustion to increase the heat loss, reduce the thermal efficiency of the chemical plant boilers. In summary, the excess chemical plant boiler operation have an adverse impact on the security and economic, should generally not excessive run. If the special emergency must also be strictly limited scope and excess power beyond the time required to force.

SZS structure which forms the water tube boiler described below common small water tube boiler: the boiler is mainly composed of vertical boiler tubes, water wall header, the downcomer, the convection tubes and other components (FIG. 3-12). It evaporation capacity is divided into 2t / h and 4t / h, which is the simplest structure water-tube boiler and a minimum capacity. In the furnace chamber, two horizontal drum of the drum water is not a vertical line in the center, minor drum forward, tubes convection expansion joint between two rollers. Seamless steel tube is curved convection bank of 51 mm formed by the outer diameter. It is arranged in a row, is provided a smoke screen between the tube wall folded, Z-shape so that smoke passes through the tube bundle. Wall and ceiling are arranged in the furnace front wall. Wall arrangement bow front lower portion of the side wall. Extracting two downcomer barrel from both ends of the boiler, through the lower wall of the header connector with the side walls of the water wall. Elbow boiler waterwall tubes and convection, readily expandable, unitary structure having a good elasticity, a large volume of the furnace, for burning various fuels. However, the use of coal workers' labor intensive; less heating surface arranged furnace surface, not the tail flue economizer, the exhaust gas temperature is high, the low efficiency; convection tubes easy to fouling. Two Longitudinal bend tube boiler drum (D-type boiler) D-type arrangement is very common in recent years, a small boiler tube arrangement, which is characterized essentially in the same vertical twin drum center line, parallel to the chamber axis double drum shaft furnace, boiler and the side of the water wall, the other side of the flues and convection heating surface tubes, D type boiler. D-type arrangement are also used in oil-fired boilers. Figure 3-13 shows a D-type boiler having a vibrating grate. Drum main ingredient is water, convection bank, Wall System, (water wall, the first downcomer), economizer , such as some boiler superheater. Slightly larger than the diameter of the cylinder barrel diameter of convection bank connected between two reels. Convection tubes of 51 mm outer diameter of a seamless steel composition, disposed in the convection pass convection pass, convection pass longitudinally along the refractory wall into two half-regions, the flue gas convection pass along a U-shaped flow. Fireplace decorative walls, all around the side walls and the downcomer is provided with fixed frame, form a closed water circulation system.
