Gas Fired Steam Boiler For Central Heating

Gas Fired Steam Boiler For Central Heating

Since December, the working out of Chishui City in Guizhou Province coal-fired boiler entered a crucial stage, ensure the completion of this year, the provincial environmental protection department issued a coal-fired boiler out of the task on time.

Chishui City Market Supervisory Authority on December 11 officially began governance, Union City Environmental Protection Bureau, City Comprehensive Administrative Law Enforcement Bureau, called the slow progress in phase-out coal-fired boilers companies and gas companies to warn interviews. It requires companies to plan prescribed time node coal-fired boiler renovation project, inverted construction, to ensure the smooth progress of renovation project.

From December 10 to 17, Market Authority law enforcement officers will be on hand daily supervision, dispatching five nine companies renovation project and construction schedule boilers, coal-fired boiler to ensure complete phase-out schedule.

First, when the flue temperature dropped to below 50 ℃ Solution: Check the tail may enter the flue if heated, while the flue thoroughly remove soot. No burning flue tail, can be re-started ignition; if burning, should be replaced, repaired burning member. Second, the combustion chamber when the negative pressure is too large Solution: When the exhaust gas temperature close to the temperature of the injected steam, or less than 150 deg.] C over 1 hour and stable, open the inspection hole inspection; after inspection after confirming the fire source, before start the fan ventilation. Third, shutdown or fire, air gun valve ajar solutions: reinforcing and electric fired steam boiler for central heating feed water drainage, or open the valve economizer recirculation tube to protect the economizer is not burning. Fourth, Kai, during shutdown lower furnace temperature, a solution of unburned fuel in the furnace: extinguishing device immediately put into vapor, carbon dioxide or other devices off fire. Five burning improperly adjusted, with insufficient wind or with the wind unreasonable Solution: Close the flue duct and baffle around the door opening, start sending prohibited, induced draft fan. These are the methods of electric heating steam boiler fast boiler to provide you with the handling of soot in the chimney, if you use electric steam boilers, with more than five can control their own boiler equipment need to be cleared up the flue, and select the appropriate method .

Fuel gas control step and the blowing process air volume of the total fuel gas fired steam boiler for central heating steam boiler is achieved by adjusting a liquid coupling scoop blower. Organization fuel gas steam boiler combustion, is to make a, air pressure, air flow of secondary air with the good. Adjusting the amount of primary air should meet it carries the fuel into the furnace ignition of volatile oxygen required, and to maintain a certain speed, and without clogging the fuel discharge pipe of the jet having a certain rigidity. Primary air volume is too large and too small, the wind speed is too high and too low, should be avoided. In addition to adjusting the secondary air of combustion of the fuel should ensure that the oxygen demand, but must maintain a certain wind speed and primary air is mixed with the master time should have a strong stirring and mixing coke penetrate "the Gray" kinetic , which requires the case may be, each layer of the secondary air flow rate, in order to achieve stable combustion and flue gas excess oxygen appropriate destination. Fuel gas steam boiler, secondary air with what is better? Primary air volume air volume of the total share is called the primary air rate. A small air fraction, pulverized coal is heated to at least the heat required for the ignition point, fire faster, but the amount of primary air to satisfy the principle of combustion of volatiles. Secondary air mixed with the primary air time to the right. If it is mixed before ignition, means an increase in the amount of primary air, so that the ignition delay; hypoxia combustion secondary air if mixed will make late after ignition; if secondary air is mixed all at one position, since the secondary air temperature well below flame temperature, the flame temperature decreases, the combustion slows down, causing the fire. Therefore, the secondary air mixed with fuel should be based on the nature of the combustion zone as required timely sent, so that the combustion of oxygen, and will not reduce the flame temperature to ensure complete combustion and ignition stability. One or two wind speed with what is better? Fuel gas steam boiler once the wind speed is high, the fuel gas stream will catch fire in places far away from the burner, the ignition point postponed; once the wind speed is too low, it will cause a blocked ducts, and ignition point is too far forward, the burner will burn , but also easy to coke near the burner.

What kind of fuel and industrial applications in the bath kind of boiler: the boiler, which is related to learning, the following, which will start with some difficult problems, to initiate and conduct specific, that is, to carry out this important product Q & A site solution confusion, thus, to advance their learning process and accelerate learning, so you can let all of you to progress further and, at the same time, to increase the amount of their own knowledge in this area. 1. boiler, the steam can produce one ton of water how much? If the boiler is used in bathing areas, then, is what fuels to use, better? Boiler, steam can produce one ton of water volume, mainly related to boiler design, boiler parameters, power boilers and boiler emissions of these four, so light so ask, the answer is not good, can not give specific value. As for question two, the boiler in the box view, the use of clean energy, such as electricity, natural gas or fuel oil, etc., is more appropriate. And coal, may bring pollution problems, not green. 2. boiler, which is used in the industrial field, it is generally what kinds there?
