Why the boiler grate burnout ?How to repair it? The reason for boiler grate damage: 1.The coal seam in the chain grate is nonuniform, furnace with too high temperature, too many imperfect combustion coal accumulation in the end of the grate slag trap keeping on burning. 2.The dam-board doesn't make regular ash-discharge, the small size coal follow down and still burn in fine ash bucket
Chain coal-fired boiler is mainly by the coal feeding system, chain gra te, boiler body, econom izer and air prehea ter and other m ajor parts. Its wor king principle is to poin t to in the proce
How to prolong the chain grate boiler operating life The longer service life of chain grate boiler can reduce investment costs,accord with the requirement of national energy saving at the same time,in addition to the requirements of maintaining a relatively stable furnace conditions by avoiding stopping,decreasing,and increasing the wind frequently,we also should take the following measures
The combustion mode of the biomass fired water tube steam boiler is light type chain grate or reciprocating grate. It is suitable for many kinds of biomass fuels, such as sawdust, bamboo chips, straw, rice husk, peanut husk, bagasse, etc. Stepless speed regulation is adopted to ensure that the fuel burns more fully on the grate and reduce fuel
2019-5-27 · 1. Place boiler in desired position. 2. Place steel shims or bricks under each corner of boiler to allow an air space, to prevent moisture from accumulating and rusting base of boiler. They should stick out 2" all the way around so the jacket has adequate support . 3. Using a level, plumb stoker end of the boiler, adding steel shims as necessary.
Coal fired steam boiler temperature regulation 1. Coal fired steam boiler temperature regulation In the operation of coal fired steam boiler,the temperature fluctuations can cause a range of hazards,the high temperatures will cause superheater tube wall temperature rise,the low temperature will affect the the gas consumption increase of gas users,even damage the equipment,so we need to adjust
2020-6-28 · 4、Adopt scale chain grate to achieve mechanized feed, feed uniformly, combustion stability, easy to control, not easy to temper, easy to cleaning . 5、Stable running, convenient to adjust, enough output. 6、Compact structure, compared with the same type boiler, it has smaller size, which save the investment of the boiler room.
2020-1-18 · Overview: SZL Series Biomass Chain Grate Steam Boiler is designed by our engineer that learn the advanced technology at home and abroad and experience, which is the horizontal type double drum Longitudinal type chain grate water tube steam boiler and hot water boiler .This series boiler has reached the international advanced level at technology, performance, environment protection.
2021-1-7 · 1) The boiler combustion chamber is composed with chain grate and large diameter coil, sufficientcombustion and high thermal efficiency. 2) The radiation section adopts square coil, and the convection section adopts serpentine coil, the heating coil has a good thermal expansibility, low stress, safe and reliable.
The ignition equipment of chain grate boiler. Spread a thin layer of coal on the grate between the coal gate and rear arch,and pave the firewood and kindling on the coal,then, start the induced draft fan,and keep the furnace negative pressure of chain grate boiler
2021-2-23 · FBC ADVANTAGE OVER CHAIN GRATE STOKER BOILER; Open the start up vent valve; ensure that minimum 20% MCR steam flow beacuse of maintain the flow through superheaters. Adjust the PA Air to wind box to start bed fluidization, ensure the air flow through windbox is above purge air flow requirement. Start the fuel feeders.
2021-3-15 · In the operation of coal fired steam boiler,the temperature fluctuations can cause a range of hazards,the high temperatures will cause superheater tube wall temperature rise,the low temperature will affect the the gas consumption increase of gas users,even damage the equipment,so we need to adjust the temperature of coal fired steam boiler
The utility model relates to a high-efficient coal scatter of a large-middle chain-grate boiler, which is characterized in that a plurality of plowshares are uniformly and vertically arranged on a rotating shaft, a positioning sleeve is arranged outside the rotating shaft, the positioning sleeve is installed in a fixed sleeve, the fixed sleeve is installed on a positioning hanger plate in a
2021-3-13 · 5. 1-20T/H & 0.7-14MW boiler adopt big and high strength grate, add rolling device improves the boilers' safety, lessen coal leakage and adjust burning conveniently. 6. Over 20T/H & 14MW boiler adopt flake type or beam type chain grate, less coal leakage, convenient burning adjustment.
The boiler is mainly composed of upper and lower drums, convection tubes, water-cooling wall tubes, down pipes and headers. The upper and lower drums are arranged longitudinally and with belt type chain grate as its combustion equipment and non-polar speed-changing device drivers.
2020-7-21 · SZL series assemble chain grate boiler fuses water-cooled arch technology and membrane water wall technology, which is domestic initiative. And the boilers overload capacity is strong and has wide adaptability of coal, so it has the world advanced level. With water-cooling arch and membrane water-cooling wall, this SZL boiler is more energy
boiler chain grate, water cooled grate: and the movement speed can be arbitrarily adjusted to adjust the residence time of the garbage on the grate according to the nature of the garbage and the burning condition. The grate inclines about 26 degrees in the furnace.
The boiler barrel and the water cooling walls on both sides constitute the furnace radiation heating surface.
