Product Description
Removable Horizontal(Vertical) Pulverized Coal Combustion Furnace
(Nation patent , Patent NO.:200710052442.0)
1 Working Characters:
I. In order to meet the current needs of energy saving in small and medium industrial boilers, this product transform high efficiency coal combustion technology into mechanical and electrical integration form.
 
II. In order to avoid excessive fouling in industrial boilers, this product takes outside-furnace slag system. The flue gas dust and ash going to the main part of the boiler only accounted for 15% of the from total combustion, of which only a small part of them submerged in the boiler, most of which going into the dust collection system outside the furnace. Industrial boiler only uses compressed air blowing system to avoid the artificial slag-digging. Effect of the use of this product is basically the same with that of oil and gas-combustion industrial boilers.
 
III. Compared with that of coal-water slurry combustion coal, we have a wider range of the kinds the combustion coal. We don't need privileged bituminous coal, and we can use common bituminous coal, anthracite, brown coal and even the low quality coal.
The burn-off rate of pulverized coal can up to 99%, carbon content in the slag is about 1%. The yellow-white slag is good mix of building materials and agricultural fertilizer, which can achieve the purpose of recycling. Compared with the general chain boiler, the coal consumption can be reduce by 25~30% or more.
 
2. Environmental Technology Data
Due to the improvements of the combustion system, we have transformed the coal layer burning into pulverized coal combustion with outside slag discharging technology, compared with the chain-type industrial boilers.
The capture rate of the combustion cylinder (vertical or horizontal) can reach more than 85%, so that the slag content in the industrial boiler is less than 15% or more. According to the basic principles Water film cyclone, we have developed two-stage desulfurization Mist filter (stainless steel and other steel products in products introduction) successfully.
Then we eliminate the water film dust removal completely, so that the boiler dusts removal system became simplified with better dust removal effect.
Then removal efficiency ups to 99%, the dust content ≤ 100 mg/m3,SO2 ≤ 250 ~ 300mg/ m3,NO2 ≤ 400mg/ m3.
3. Achieving PLC Automatic Thermal Instrumentation Control System
It changes poor working environment of the chain-type industrial boilers burning completely and reduces labor intensity in the chain-type coal-burning industrial boilers greatly. What's more, it also realizes using the thermal data of coal measures, machine current, voltage, furnace temperature, working pressure to instruct the production line. Then it makes the cost of machine operation more clearly, bring advanced technology and measure to reduce consumption and emissions in many Chinese small and medium chain-type boiler.
 
4 Improve the Energy Structure:
In order to meet worldwide green energy and renewable energy requirements and have further CO2 emissions reduction, this product can use double materials-- pulverized coal and wood flour, as fuel.
Spurted by wood powder bunker and wood powder blower, wood powder and pulverized coal can injected into the combustion cylinder at the same time, whose burn-off rate can reach 99% and the slag content can reduce to 2% ~ 3% . Its wood ash is a good mixed material for agricultural fertilizer, and its slag is also a good mixed material for building. You can adjust the ratio of wood powder and the pulverized coal according to their heat capacity, while avoiding economic decline due to the lack of wood (straw, wood) in some areas.
 
5 Energy-efficient Technological Transformations for 4 T~ 20T Industrial Boiler:
After equipped with energy-efficient coal burner and connected with pre-combustion cylinder, 4T ~ 20T / H steam (hot water) boiler can cut out the chain of the chain-type boiler , bottom blowers, the gate of steel warehouse and coal feeder, and screw slag discharging. It's the complete simplification of horizontal or vertical industrial boilers, just reserving water wall ( water wall in chamber should be equipped with refractory belt), upper and lower drum, in and out water system, coal economizer, air preheater and secondary air fan. Thereby the weight and cost of the boiler has been greatly reduced. Moreover, in order to achieve the best energy-efficient technological transformation for industrial boilers, we should have more specific analysis on practical conditions.
In short, the main features of our product are:
1. outside furnace slag discharging (both dry and liquid), slag-catch rate up to 85%;
2. Cyclone combustion cylinder (horizontal or vertical), pure flame with little ash;
3. The burn-off rate of fuels (coal, wood flour, straw powder) up to 99%, yellow-white slag (good recycling mixed materials for agricultural and building material).
 
6 Product Applications:
It applies to 4T ~ 20T / H small and medium sized industrial steam (hot water) boiler, and other no-oil and no-gas industrial furnaces which not allow ash contamination. At the same time, it can provide qualified high temperature flue gas and high-temperature air flow and reducing the cost of industrial boilers.
When selecting the energy-efficient technological transformation project for industrial boiler, or purchasing the accordingly industrial boilers, you should provide industrial analysis of local coal, the steam (hot water) volume of boiler, steam pressure, the size of working place, the requirements of automation and other related data. Then we can make more accurately selection for you and provide better and more complete service.
