Low calorific value burner

Boiler gas burners

Description

Coal gas  Burner are generally divided into blast furnace gas burners, producer gas burners, coke oven gas burners, and blast furnace gas burners. Because the calorific value of gas is generally not as high as that of other combustible gases, gas burners are also called Low calorific value burner.

Producer Coal Gas Burner parameter:
Coal Gas Burner
BNCF Series producer/generator/power/air/furnace gas burner used in today's world of advanced combustion technology, with reference to international and domestic standards, in order to meet the producer gas, flammable chemical tail gas and other types of combustible gas and mechanical and electrical integration of the design and manufacture of automatic split type generator gas burner, widely used in steam boiler, hot water boiler, thermal oil boiler, direct-fired lithium bromide air conditioning unit, air heating furnace and other industrial kiln, etc.
 
Characteristics of producer/generator/power/air/furnace gas: flammable and explosive, gas itself has a certain toxicity, industrial production of gas quality and pressure fluctuations, producer/generator/power/air gas components are not fixed, with the fuel which is different types of coal and different operating conditions fluctuate within a certain range.
 
Our company adopts high calorific value fuel (natural gas, liquefied petroleum gas or light oil) to set a long open flame in the design, so as to ensure the stability and safety of flame in case of fluctuation.
 
Adaptive fuel:1100kcal/Nm3≤Gas calorific value<2200kcal/Nm3.

BNGJ Series Coke Oven Coal Gas Burner :
 
BNCJ Series coke oven gas burner used in today's world of advanced combustion technology, with reference to international and domestic standards manufacturing mechanical and electrical integration of the automatic separation burning coke oven gas burner, the products are widely used in steam boiler, hot water boiler, thermal oil boiler, direct-fired lithium bromide air conditioning unit, air heating furnace and other industrial kiln, etc.
 
BNCJ Series coke oven gas burner has a wide power coverage and is suitable for boiler tonnage 1T/h to 40T/h.
 
Due to the low calorific value of coke oven gas, and most of it has not been purified or treated thoroughly, the gas contains coal tar, dust and other substances that are easy to block the pipeline. Therefore, the ordinary burner cannot achieve long-term continuous operation when using coke oven gas.
 
BNCJ Series of coke oven gas burners for coke oven gas low calorific value, low gas pressure and high impurity content and design of the special burner, both retained the one-piece automatic burner combustion stability is good, high safety performance, but also has the coke oven gas resources can be fully and safely use of the characteristics of good product is the use of coke oven gas.
 
Adaptive fuel:2200kcal/Nm3≤Gas calorific value≤4500kcal/Nm3.
 
After the corresponding parts are modified according to the requirements, it can adapt to high temperature combustion air below 250 ℃.

BNGC Series  Blast Furnace Coal Gas Burner:
 
 
BNGC Series bf gas burners are designed and manufactured according to the combustion characteristics of bf gas and the relevant international and domestic standards. They can be widely used in steam boilers, hot water boilers and other industrial furnaces.
BNGC Series of bf gas burners gas valve sets, programmed controllers, damper actuators and other famous brands are used to ensure excellent burner performance, safety performance and reliable operation.
 
Features of Our Blast Furnace Coal Gas Burners For Industrial Furnace And 1 To 25 Ton Boilers:  
 
In view of the characteristics of low calorific value, difficult ignition, easy deignition and slow reaction speed of blast furnace gas, the design and manufacture of the blast furnace gas burner adopts the three-stage combustion mode, namely, the three-stage combustion of high-calorific value fuel is ignited first(Such as natural gas, liquefied gas)And as a part of the constant open fire ignition gas(Auxiliary gas)The main coal gas is ignited after stable combustion. The inner part of the burner is arranged with a heat-resistant stable combustion chamber. The gas and air are mixed in the circular slit with swirl vane and then spurted out for combustion, ensuring combustion stability and sufficiency.
 
Adaptive fuel: 600kcal/Nm3≤Gas calorific value<1100kcal/Nm3.
 
According to the requirements of the corresponding parts of the transformation can be adapted 250℃ below high temperature combustion air.
