steam boiler pellet high pressure low coal gas
An clients from Bolivia, contacted with our service staff online, he wanted to know the price of 5 ton biomass steam boiler pellet high pressure low coal burning sunflower husks. Our Bolivia client owned a food factory which needs 5 ton steam per hour in food process. Then, our sales manager contacted with him online, and got more details about his requirements of this 5 ton sunflower husks biomass boiler. In details, our clients wanted to burn sunflower husks and coal together. This is a good idea. Because only burning sunflower husks, the boiler can not reach to a high point in thermal transferring process on fire at once. But with coal fuel and husks mixed, this chain grate boiler can soon improve burning efficiency on fire stage.
Group multiple departments quality systems, technology department, production systems, development systems, with the assistance of outside experts, please, to overcome the difficulties, overtime, and fulfill all the preparatory work. Assessor staff often give up personal time off from work carried ASME study and training, frontline staff overtime for practical operation of the exercise. All those involved in the trial personnel in the company "professional life, work lean" under the guidance of the core values of continuous fighting, the various problems couplet review group proposed were closed, one-time passed the ASME certification.
Greater than 65t / h industrial boiler of what air pollutant emission standards should be executed? A: The State Environmental Protection Administration, Central Division-standard  No. 012 document pointed out that the emergence of a small number of parameters currently higher than GB1921-80 "industrial steam boiler pellet high pressure low coal parameters Series" and GB3166-82 "hot water boiler parameters Series" layer burning, stoker boiler, regardless of its use Zanan GB1327-91 execution. Therefore> 65t / h or more (except coal, circulating fluidized bed, and fuel, gas fired boilers) industrial boilers should be performed "boiler air pollutant emission standards."
Steam boiler accident type and processing method, and use common sense safety boiler steam boiler pellet high pressure low coal accident type and processing method, overpressure accident 1 boiler, boiler overpressure phenomenon of (1) a sharp rise in steam pressure, exceeds the allowable working pressure gauge pointer over " red line "safety valve after the pressure is still elevated. (2) the operation of the device is the interlock overpressure protection, should send overpressure alarm signal, stops the air blowing, the wind, coal. (3) steam temperature and steam flow rate reduction increases. 2, to treat boiler overpressure (1) weakened rapidly burning, manually open the valve or bleed valve. (2) increase the water supply, while the lower reinforcing blowdown drum (It should be noted at this time to maintain the normal water level of the boiler), in order to reduce the temperature of the boiler water, thereby reducing the pressure in the boiler drum. (3) as a safety valve malfunction or all of the pressure gauge damage, emergency shutdown, safety valves and pressure gauges are to be repaired after the boost operation. When endanger the safe operation of (4) Boiler excessive pressure, blood pressure should take measures, but too fast buck is strictly prohibited. (5) boiler overpressure eliminate serious, to the shutdown of the boiler internal and external inspection, to eliminate the overpressure caused by deformation, leakage and other safety accessories and maintenance unqualified. Second, an accident boiler water, boiler water shortage (1) below the minimum safe water level line, or can not see the water level, the water level gauge glass (plate) as a white. (2) as a full-color water level gauge vapor instruction color. Low water level alarm signal (3) water level alarm occurs. (4) low water interlocking means, the water level should be below a prescribed value blower, Fan, grate reduction motor stops running. (5) a sharp rise in the superheater steam temperature, higher than the outlet steam temperature. (6) boiler exhaust gas temperature rises. (7) the water flow is less than the steam flow, causing Should the water tube due to tube cracking or economizer, an opposite phenomenon occurs. (8) When a serious water shortage, can smell the burnt smell. (9) When a serious shortage, the door can be seen from the red-hot waterwall tubes. (10) a serious water shortage, the furnace tube may rupture, then can hear the explosions, smoke and steam from the door, watching spray the fire door. 2, boiler water treatment (1) through the "waters", sentenced to severe water shortages, emergency shutdown must be prohibited blind to the boiler feed water. (2) through the "waters" sentenced to a slight lack of water, it should reduce fuel blast, the wind, and slowly feed water. Third, full water boiler 1 accident phenomenon (1) above the maximum allowable water level line, or can not see the water level, the water level gauge glass (plate) dark color boiler filled with water. (2) all of the water phase as a color level gauge indication color. High-water alarm signal (3) water level alarm occurs. (4) decreased superheated steam temperature. (5) water flow is not normally greater than the steam flow. (6) water in a large number of sub-cylinder, severe trap operation. (7) with a large amount of water steam severe, increased salinity, water hammer occurs in the sound of the steam pipe, the steam connection flange outwardly dripping take place. 2, boiler full of water treatment rinse water table, determined to be minor or serious full of water full of water. Method: Close water table, the water pipe connected cock, then open drain cocks As can be seen from the decreased water level, indicating a slight full of water, the water supply is stopped, the drain valve open, put to the normal water level. Such as severe filled with water due to take emergency shutdown measures.
