4 ton DZL coal fired steam boiler

What is its auxiliary boiler feedwater oxygen has several categories? Boiler, I believe we are not unfamiliar with and understand it, if you have been concerned about the site and read the relevant article and master the relevant knowledge and content words, so below, it may be in front of the existing foundation, to continue the products of study and work, so that we can make progress in their learning and development road, and at the same time, you can also reach the intended target as quickly as possible. 1. ship boilers and boiler land, they are the same? Can GM? Marine boiler, which is used to generate steam, or fuel for heating domestic water, and may also be in the kitchen in the ship. However, it is compared with a land boiler, there is a big difference, such as shape and size. So, they are not identical, nor is it universal. 2. auxiliary boilers, there are a few main categories? Auxiliary boilers, which can be divided into six categories, the specific terms, it is the coal slag or counseling classes, containers, water treatment class, class fans, smoke and dust classes and appliances category. Wherein an expansion device containers, and other such sub-cylinder, the fan type blower and is mainly induced draft fan. The appliances, mainly for electric and control these two aspects.

Mature technology in biomass boiler, our SZL series chain grate boiler widely available renewable energy technology that generate steam from 6 to 40 ton to any industry factories, facilities, plants, etc. What’s more, our ZG Boiler can can supply larger capacity and high pressure circulating fluided bed, power plant boiler, biomass boiler, produce steam for electricity or other requirements. A fully automated operation system, similar to those used for conveying feed and grain on farms, delivers biomass pellets from an outdoor silo to the boiler’s hopper. At a rate predetermined by user-controlled settings, a fuel-feed system then delivers the pellets to a combustion chamber. Pellets are burned using staged combustion air injection (a process that reduces NOx ). A cyclone separator knocks out particulate matter that is then removed by an on-line, automated mechanical cleaning and ashremoval system. Usually, biomass fired cfb boiler has higher thermal transferring efficiency than chain grate boiler. And both of them can burn mixed fuels like wood pellet and coal; bagasses and coal; palm shell and coal etc.

After the gas hot water boiler hot water boiler vaporization emergency 1. Vaporization handler circulating pump stops abnormally pump failure caused by: ① blower stops running immediately. ② immediately open the door, take measures to pressure the fire, lift the chute gate, cutting off the supply of coal grate. ③ In the case of boiler pressure not greater than 0.6MPa (600KPa), the exhaust valve to follow, only a sharp rise in pressure in the boiler deflated, used only relief exceeds 0.9MPa, and the exhaust process to be carried out slowly, prevention boiler due to loss of pressure and more violently again vaporized. ④ close the boiler water, water main gas valve. ⑤ open stop valve recirculation line, to ensure that the water supply pipe velocity convection heating surface (economizer) to prevent re-vaporization of the economizer. ⑥ The operation of the above operation, at the same time to pay the boiler to reduce the boiler water temperature and the furnace pressure. ⑦ After the boiler pressure is normal, i.e., opening the standby circulating pump, into the normal combustion. 2. Treatment failure or sudden loss of power boiler vaporization of power: ① immediately open the door, lift the coal chute slide gate to take pressure fire measures to reduce the oven temperature. ② Grate with the fastest speed in order in the shortest time to fire onto the slag tap. ③ the degree of treatment in the first case. Once a short time can not supply heating network system, antifreeze should take emergency measures. 3. Due to excessive heat boiler boiler vaporization process: ① the immediate closure of the drum, induced draft fan. ② immediately open the door, take measures to pressure the fire, lift the supply of coal chute slide gate, off of coal, while the grate into fast gear. ③ In the case confirmed the presence of water, the boiler can supply water to the boiler body, boiler out of the water while closing the main valve. ④ Open line stop valve recirculation pump to ensure water velocity convection heating surface of the pipe, to prevent the economizer again vaporized. ⑤ Open circulating pump with jog mode, jog each time less than 30 seconds, again less than one minute jog interval. Jog purpose is to reduce the boiler water temperature, while preventing a large amount of steam into the pipeline system. ⑥ back into place after the safety valve, circulating pump running, and then the normal burning stove. 4. Water boiler system run vaporization process due to water loss, loss of pressure caused by: ① immediately closed drum, induced draft fan. ② out of the water while closing the main valve and the boiler circulating pump. ③ take the same measures to cool the furnace tube described above. ④ Open stop valve recirculation line. ⑤ rely exhaust valve until the safety valve back into place. ⑥ until the boiler water temperature drops below 50 ℃, when the temperature of the furnace temperature less number 200 ℃, again within the boiler feed water, water course to be carried out slowly, to prevent harm to the boiler when the temperature is too large. ⑦ After processing leakage fault, the system time to the replenishment, and out of the water boiler always open the valve, and the circulating pump, and then normal combustion.

To ensure the safety of special equipment such as boilers, in normal use, to further promote the comprehensive management of environmental pollution, since April this year, Khorgas Market Supervision Administration of Quality Supervision Bureau for the joint Yili area within the jurisdiction of Khorgas , launched a special safety inspection activities boilers.

Law enforcement officers to be included within the jurisdiction of the major hazard of 12 boiler units of a total of 21 boilers individually conduct a special inspection, focus on examination of the "three implementation, two certified, a test, a plan," the implementation of a detailed view of boiler safety management system, run records.

Test results showed that most of the boiler unit security management more standardized, but there are still some units use boilers run records were incomplete, part of the boiler has to inspection cycle, has been scrapped or dismantled boiler is not write-off and other issues, law enforcement officers to issue on-site boiler sealed, and ordered boiler unit for rectification.
