iteration blues

So, I wrote this code for some particle effects:

package com.coolfone.particles;

import java.util.Iterator;
import java.util.Vector;

import javax.microedition.khronos.opengles.GL10;

public class FireManager {
    static Vector<Particle> particles = new Vector<Particle>();

    public static void startfire(float x, float y) {
        for (int ctr = 0; ctr < 100; ctr++) {
            Particle p = new Particle();
            p.x = (float) (x + Math.random()-.5);
            p.y = (float) (y + Math.random()-.5);
            p.dx = (float) (Math.random()-.5)/4f;
            p.dy = (float) (Math.random()-.5)/4f;
            p.timeleft = (int) (Math.random() * 50 + 50);
            particles.add(p);
        }
    }

    public static void burnfire() {
        Iterator<Particle> i = particles.iterator();
        Vector<Particle> removelist = new Vector<Particle>();
        while (i.hasNext()) {
            Particle p = i.next();
            p.move();
            p.timeleft--;
            if (p.timeleft == 0) removelist.add(p);

        }
        particles.removeAll(removelist);

    }

    public static void drawfire(GL10 gl) {
        Iterator<Particle> i = particles.iterator();
        while (i.hasNext()) {
            Particle p = i.next();
            p.draw(gl);
        }
    }

}

I'm concerned about inefficiency in the burnfire function. Does
anyone know how to rewrite this quickly if particles was a linked
list? The main issue is that I'm not sure if removing items during
iteration messes up the iterator.
